  1. '72 was 1st year... 14% of cars had it. Nothing available earlier. Cadillac in the'60s had power passenger buckets...but it was 2 way only! Darwin Falk 1966-70 ROA Technical Advisor
  2. Great News Jon... a good investment. There's a 95% chance that this is a legitimate '66 Riviera GS. As other posts have mentioned, it is not terribly hard to clone one... but cloners rarely get all the little clues right. Of the visible ones, they're all there and as expected. To confirm further, we'd need to see stamped codes. The car was originally Riviera Silver Green...but this is definitely not that color. (Actually, this color looks nicer to me... closer to a Turquoise mist). For top dollar like this, if the color isn't an exact '66 Riviera color, it harms value ... (I mean, it loo
  3. The reason '66 are different from other Buicks is that they had a real ammeter gauge and so the cars' wiring is slightly different than others. Luckily, for '67 they did it differently so a '67 switch fits all the '67 Big Buicks... but that's it. At least slightly more common than the '66 one is. '68s had different connectors ... then '69 and later are in column. So not much to interchange with. Each GM division used their own switches. A '66 one is easily worth $150 NOS and a '67 at $110-130. I certainly wouldn't sell either one for less... too impossible to replace. ' Even a ke
  4. A version of sales codes were used in '63's body plates and on later year GM cars that were made at other assembly plants. Fisher's body plates for '64 through '67 use option codes that don't bear any relationship to RPO codes or sales codes. 3B is rear defogger for all 4 years, '64 to '67. The 'pattern' of the groups used on Fisher body codes isn't very 'strict'... generally speaking options with lower group numbers are bigger ticket items while the last groups, 4&5 tends to be 'fluff' that would be last installs. Group 1 are big ticket items...very fundamental to the car like glass, po
  5. This is partially correct. '65s are like '66s, the VINs are quite sequential among Rivieras, but with a few outliers. For '66, a small number of Wildcats built in Flint have sequenced Vins among the Rivs. I have documented quite a few '65s over the years... earliest for me was 6,471 from November 3rd week 1965 up to 52,043 for a 3rd week of July car. Given how late this last one was built, I seriously doubt there are more than a handful beyond 52,043. With the known production of Rivs for the year, there are a few non Rivs in with them as you can see. Those of you who attend ROA Meets hav
  6. I agree with Ed's interpretation. Caps were installed at the dealership. While it was available at factory or as dealer option, the caps (as well as all wheelcovers) were installed upon arrival at the dealer. A sheet I'd never seen before either... I wasn't aware of the 2 rim widths for 7.1 vs 7.6" tires. Darwin Falk 1966-70 ROA Technical Advisor.
  7. I've previously covered some of this discussion in previous "Options Not Included" articles in the Riview. ACRS is quite rare... only 329 '74 Rivieras had it... not experimental...just another option you could get if you spent the money. Obviously not popular. A separate service manual was issued in '74 and '75 for the system. There was a tank mounted along the lower side of the passenger dash that held the inflator gas under high pressure. It is about the size of a small fire extinguisher... 10 1970 Rivieras had ABS brakes on the rear wheels. It was not regularly offered as an option...
  8. Well, I'm pleasantly surprised. I got OPGI's catalog for the '50s '60s '70s Cadillacs in the mail today. Many/most of the items are reselling of other people's products of course... but seeing all the reproduction stuff photographed / described in full color in one book was a great experience. There are a couple Eldorado items I'll be ordering ...that fit Riviera too. If they do approximately as well for Riviera as they did for Cadillac then we're in for a whole different buying experience than any of us are used to (well except for those Riv owners who have a Chevy in their garage too).
  9. September marks the 1 year anniversary of their ads. So far, the only thing they have is a picture of a catalog cover. Not an impressive start... Darwin Falk ROA#2077

  11. 1a)This is the most difficult piece of trim to install on 2nd generation Rivieras. If your paint is extra thick, you might even need to sand it down a bit to get a fit. Best way is to start at the apex of the curve and work your way out carefully. You must get the curve matching very closely or you will have problems. ... you want to start outside edge and pull it down and in bit by bit working to the ends. Work to the back lower edge first... then the longer distance to the front edge. A 'church key' with a little electrical tape on it was my tool. 2) No 3) removal of 3 of the 4 bolt
  12. Generally speaking, most non-disc brakes on '68s are Delco Moraine and ALL disc brakes are Bendix. A further clue is that the Delco MOraine booster is of larger diameter and unpainted (originally gold cadmium finish). A Bendix booster is a little smaller in diameter, has a smoother 'face', and is painted black. Darwin Falk 1966-70 ROA Technical Advisor
  13. From what I've seen, belts are like original factory hoses... they have the part number printed on them, in white ink from what I've seen. No indication of who manufactured the belts for Buick/GM. Darwin Falk 1966-70 ROA Technical Advisor
  14. Only a small number of Toronados had shoulder harnesses in '67, on deluxe models, 1.5% of total production. The belts could be either the 'deluxe' ones (chrome metal buckles) or standard (black buckles). The standard are very very rare. (Man, I'd love to find a parts car that had harnesses... nice!) In theory, you could be looking at the difference between deluxe and standard belts. However, my experience with a '67 Eldorado is that the holders on my car are plastic. So... barring additional evidence, I think plastic is more likely correct for both deluxe and standard belts. The plastic
  15. Number 44 is the one that came with the '66 from the factory. 42 has wires built into the switch... this gives it away as a Delco Remy Switch used in earlier years but not at all in '66 or '67. 1966's have the wiring built into the harness so the wires on 42 make it unusable in '66/67.... The '66 switch is made by "Littlefuse", not Delco Remy according to the parts book. A cable/adapter was introduced and sold to allow use of the later switches in earlier cars. Never seen a style 43 before. 41 is a second style of 44. Shop manuals and parts books say that '66 and '67s used the same switch
