Good explanation, but I still don't understand completely why. It wasn't a matter of the price line of the car; '55-'56 Dodges came with lug nuts, Plymouths, DeSotos and apparently Chryslers and Imperials with lug bolts. --Roger ----- Original Message ----- From: "George E. McCollam" <McCollamGE@xxxxxxxxxxxx> | HI, Yes I can add some light. It is correct to have 'Left hand' thread | on the driver side, all mopars of that era had left thread on that side. | One reason for the lug bolts instead of lug studs on the rear, is that | you have about two inches less of obstruction to changing a reat tire, | (although that not so important on your car with the full wheel opening) | if you had studs it would be a tighter fit. But, I believe that for | what ever reason it was more cost effective to manufacture that way, | also it is said that lug bolts are stronger than lug studs, don't know | for sure how true that is, but alot of heavy equiptment, trailers, | especially horse trailers used this method. You should have a small | locating pin between two of your rear studs this pin fits into the small | holes between the rim lug holes. If it is gone, it may have been removed | at some point so that a more modern rim could be fitted, also the center | hole of the rim should fit snugley on the axel center flange to hold the | weight of the tire when mounting. Hope this helps. | George ... 'with the soon to be beautiful '55 &'56 Limo's'
