Randy, this is not really a cut and dried situation. Several factors are involved in making the determination you want. You need to determine what size tire to run, front and rear, because the section width of the tires will be the determining factor. Add to that suspension. Yours stock? Stock 60 years ago, or springs replaced? If your GS had the handling package option, those springs are different as well. Backspacing is also important. Custom wheels mean you can specify a backspacing wanted. Need to keep both of these near stock at 3 5/8”. At least you won’t have to deal with the larger 63-64 hub centers or left hand thread lug nuts I did. Speaking of, lug nuts are 1/2 -20, nut 7/16. Also, front hubs are riveted to the drums. These rivets are between the studs and may or may not fit into a depression in the mounting surface of the wheel. May have to remove the rivets or clearance the wheel mounting surface. You have chosen a good looking wheel, but not sure anyone here will have the answers you seek without more info. Maybe not then.

Dog dish hub caps? I didn’t think Buick offered these at all, and Riviera specifically did not. Unusual photo. July-August 62? Google says December, but not sure.

Don’t know and not defending Anthony, but Houston was hit hard by tornados this weekend and still has a lot of power outages. Just saying…

Think of this bunch as your group therapy. Keep at it. Don’t lose the faith.

Add grind and repaint to this as well.

John, pattern is the same for the heat riser and the rams horn. You will be good. McMaster Carr has brass nuts, but may have minimum order and shipping issues to you. Worth a check. www.mcmaster.com

Cast valve covers are taller and more square at the top. Sheet metal covers are shorter and rounder at the top. Regular bracket can be modified to work. Have to remove material on the inside of the bracket on three sides. Close to a quarter inch at the top of the arch of the bracket. Work slow and check often for clearance.

Hate to argue, but these are Chevy car rallies. Chevy truck rally’s have a different center. 15x8 for trucks, 15x7 for vans, but I have seen these in the aftermarket up to 24s.

Really telling your age with OTASCO and Fox Craft, ya know? Oklahoma Tire And Supply Co. has been gone since the early 70s.

You want screaming, drive my 55 Chevy with a Turbo 400, 4.56 gears, and a G70x14 tire. Thought I would never get that car home. Love the car, but not one for a day trip.

EmTee, also remember GM trucks and vans didn’t get locks and switches on the column until 73. Still in the dash through 72.

Go talk to Max at American Transmission on S. Walker in OKC. 405-631-1386. If you are in OK, half the battle is won. Max also has a gorgeous 67 Riviera and a great 55 Chevy hardtop. He is your guy.

Make the change. You will be glad you did. Unless you just abuse these, stock drums are fine. Big difference with dual cylinder and modern booster. I went through this almost exact same thing several years ago.

Only a couple of small errors. At 2:10 is an oddball engine. 63 vacuum tank, black air cleaner (64) dual master cylinder, aluminum valve covers and a ribbed valley cover that was never on a production nailhead that I know of. Later battery as well. At 2:40, a 425 cubic engine is noted as optional. What is overlooked is that this was a late year add and available to only a small percertage of Riviera buyers. And at 3:09 is a picture of a 63 with a 65 grille and hidden headlights in the fenders. It also has a stand up hood ornament, making it a 64, not a 63. But overall an interesting video.

Not sure if Bill is sending you a PM for a new bolt or a new housing, but it would be easier to just get a new complete housing with all 4 studs than trying to replace just one stud, based on your questions of how to do it. Bill can supply that as well.
