Guest Grapeman Posted June 28, 2016 Share Posted June 28, 2016 If anyone is considering replacing LF wheel studs on Gen 1 Riviera, I just did it. I purchased standard Dorman studs # 610-441, pressed out the old studs and pressed in the new right hand treads. I am running a 5/16 " spacer because I am using "newer" rally rims. They work fine and there is no problem. Upper is stock left hand thread and lower is new dorman. Link to comment Share on other sites More sharing options...
MaineDoc Posted June 30, 2016 Share Posted June 30, 2016 Forgive the stupid question but are studs on left side of early Rivieras left hand thread? I thought only early molars were like that. Link to comment Share on other sites More sharing options...
RivNut Posted June 30, 2016 Share Posted June 30, 2016 (edited) Yes. Early molars are followed by wisdom teeth. I do not know anyone whose molars are threaded so I can't confirm that. Edited June 30, 2016 by RivNut (see edit history) Link to comment Share on other sites More sharing options...
MaineDoc Posted June 30, 2016 Share Posted June 30, 2016 Damn spellcheck! Should be Mopar! So are they left hand threads on the left side? Link to comment Share on other sites More sharing options...
Riviera63 Posted June 30, 2016 Share Posted June 30, 2016 The answer is yes. My 63 Pontiacs that I had previous to my 63 Riviera also had left-hand thread on the left side. Bill Link to comment Share on other sites More sharing options...
patrickaturner Posted July 1, 2016 Share Posted July 1, 2016 Hi @Grapeman, Are you running the spacers so your new wheels will clear the stock hubs? I bought an aftermarket set of wheels but they won't fit around the hubs on my 1963 Riviera. Did you need to install longer studs to make your wheels fit properly with the spacers? Thank you, Patrick Link to comment Share on other sites More sharing options...
Guest Grapeman Posted July 1, 2016 Share Posted July 1, 2016 Quote Patrick Yes, you need to run spacers, at least 1/4 inch. I am using 5/16 so the rim will sit flat on the brake drum. The spacer I used in the uni-lug 5 on 5 spacer. On the holes on the spacer that are not used for the lug bolts fit nicely over the protruded "rivets" that are on the drum. I am using the later rally rims. They have no center ring on the rear. These are called the 895 rims. As far as I can tell the only difference between these and the early rims is the backspacing. The early rims have 3 3/8 back spacing and the newer rims have 3 7/8 backspacing. I did not find it necessary to use longer wheel studs because I am using the "acorn" style lug nuts and they work fine. Link to comment Share on other sites More sharing options...
RivNut Posted July 2, 2016 Share Posted July 2, 2016 No matter which way you go make sure that you have ample threads making contact. You don't want just one or two turns of the nut to tighten them all the way. Link to comment Share on other sites More sharing options...
John Posted July 2, 2016 Share Posted July 2, 2016 Anyone know if correct style chromed or stainless acorn nuts are available with LH threads? Link to comment Share on other sites More sharing options...
RivNut Posted July 2, 2016 Share Posted July 2, 2016 Look on Summit Racing or JETS for Mopar lugnuts. The last I knew, Gorilla still made them. 1/2" x 20. Link to comment Share on other sites More sharing options...

It's not just the lug nuts, also the left side spindle nut. Link to comment Share on other sites More sharing options...
