  1. 65 buick riviera kickdown switch

    There is one on ebay right now. Without it, you won't get high stall off the line, so acceleration will suffer.
  2. 65 buick riviera kickdown switch

    Sorry, this is not correct. The switch pitch trans only has two wires going to it, one +12V switched for the kickdown and one +12V switched for the converter. Converter control is the top terminal in this photo. The correct kickdown switch has one output wire for each of these functions and a single 12V hot wire coming in. As I noted above, the additional two terminals on the kickdown switch are the "piggyback" terminals for the low speed switch on the dashpot. The dashpot simply plugs into the kickdown switch. The dashpot mounts in front of the carb so the throttle arm actuates the switch at idle.
  3. 65 buick riviera kickdown switch

    The ST400 (TH400) in your car has a switch pitch torque converter. The angle of the stator vanes in the torque converter are varied to change stall speed and thus torque multiplication. As with the kickdown, the converter is controlled by an electrically operated solenoid valve. The connector on the side of the trans should have two terminals in a "T" orientation. The top of the "T" controls the converter solenoid valve; the other leg controls the kickdown solenoid valve. The kickdown solenoid is only energized at wide open throttle. The converter solenoid is actually energized at WOT and at small throttle openings. This off-idle actuation of the converter allows for additional torque multiplication off the line. As a result, there is a second switch that is closed when the throttle is at idle and just off idle. Usually this is a dashpot with a switch built into it - that switch plugs into the two terminals on your kickdown switch.
  4. 1969 Buick Riviera

    I've found that many people today try to incorrectly use the term "special order" to mean "not bought off the lot". I suspect this is yet another attempt to try to artifically inflate value, like sellers who tout unpopular body styles as "rare". Custom selecting regular options to tailor your new car was the normal way to buy cars in the 1960s. There's a reason why they were called REGULAR Production Options (RPO).
  5. Will the orphan car survive..

    Why does anyone in the automotive hobby pay any attention to articles about cars written by Bloomberg, MSNBC, CNN, etc, etc? These people are not experts in this field.
  6. Broken Manifold

    We still don't know what engine this fits or if a replacement is readily available as opposed to all this discussion.
  7. RockAuto is not a reliable source of part fitment info. The errors in their online catalog are legend. For example, if you search the RA catalog for Oldsmobile motor mounts, nothing shows up. If you search by part number for Anchor 2261, you find out that RA sells them for about $4 apiece (as compared to Olds specialty vendors who sell the exact same Anchor parts in the same boxes for TEN times that amount). I rarely even use their catalog anymore. I research part numbers through other sources then search RA by part number. There are a myriad of sources for this info - factory parts books, service manuals, marque-specific forums, etc. Hollanders is just one resource. I bought a paper copy covering the years I care about (1964-1974) several decades ago. For GM cars, many of the parts books are available on line at
  8. Inline fuse links

    Are you talking about the fusible links? Very commonly used on GM cars of this vintage. Why do you think you need to replace them? And FYI, if you change them for something else, that's not "restoring", that's "modifying". Certainly you can use a maxifuse instead of a fusible link, but again, if the originals are not burned out, why change them?
  9. That's called Hollander's Interchange Manual.
  10. Broken Manifold

    And a properly welded repair will be just as strong as original. Don't make this harder than it is.
  11. I'll add a few thoughts. First, eBay has a very powerful search engine. I have written very targeted search scripts. Unfortunately, eBay also teaches sellers how to add search terms to ads (ie, "fits: Oldsmobile") even when not appropriate, so the signal-to-noise ratio still sucks. Second, many sellers have no clue as to what their items actually are or have misspellings, so a tightly targeted search can miss these. Frankly, uninformed sellers usually give you the best deal. Finally, for many of us, the thrill of the search for parts is a big part of our enjoyment of the hobby. This is why we scan row after row of rusty, greasy junk at swap meets. Often you find something you didn't even know you needed.
  12. Broken Manifold

    Welding cast iron isn't that hard. Find an old-time welder who specializes in fixing farm equipment. We have one such person in town and he repaired the same sort of broken ear on my friend's Ford exhaust manifold. He's also welded a cast-iron drill press base for me and it's been fine for nearly 20 years now. All it takes is using the correct rods.
  13. Any reputable pot metal restorers out there?

    I have personally seen excellent results from Qual Krom in Erie, PA. They have even repaired broken pot metal emblems and plated them. The process is extremely labor intensive, and thus priced to match. By the way, it is not necessary to spam the exact same question into every sub-forum on this site.
  14. larger size tires on the rear of a 1930 car

    The speedo difference and effective gear ratio differece is simply the ratio of the tire diameters. If the old tires are 26" in outside diameter and the new ones are 27", the difference will be 1/26, or about 4% higher effective gear ratio (and thus about a 4% slow reading on the speedo) with the taller tires. Of course, the 4% higher gear ratio means slower acceleration. Of course, these are theoretical numbers assuming a rigid tire. The tire is never at the nominal diameter, as it compresses a little under load. This naturally reduces the effective radius, which makes the tire seem "smaller" in diameter. Bias ply tires flex less than radials due to stiffer sidewalls. The dimension that really matters is called "rolling radius", which is the effective radius under load. Big truck tires usually have a revs per mile spec, which accounts for this reduced rolling radius.
  15. 1966 Impala convertible, help with identification

    I have to disagree with this. The "anything was possible to special order" story is nearly always used to justify an overpriced one-of-none car. GM did not randomly install parts and ship undocumented cars to the general public. Sure, custom stuff got built for magazines and the like, but cars that were delivered to paying customers with a warranty needed to have full documentation for the dealer to be able to service them. Mid-year equipment changes did take place, but these were fully documented in service bulletins and the like. To Matt: what's the two letter code on the tag on the side of the TH400? That's your best bet to tell where it came from. It sounds like this car has been assembled from parts. The fact that the cost of doing that likely exceeded the value of the car never stopped me from doing something similar.
