1970 Duster 14/4 Rear Wheel and Tire Combinations

What about wheel adapters to get him to 5x4.5? Are they worth it or do they just create other problems? I've never used them but known some who have. Seems like most people love em or hate em.

Depends on the wheel adaptor. The cast aluminum ones from Trans-dapt are terrible. There is not enough material around the studs and they end up cracking. Which turns a lot of people off of spacers/adaptors completely. But like anything else, if you buy good parts, like an adaptor made from billet aluminum, and follow the damn directions, like making sure they're torqued properly and periodically checking to make sure they're still torqued properly, they'll last forever and never cause you any issues.

Good ones look like this

The problem with ALL of them is that they widen the track width. The good ones are usually 1" thick, which means that you need to add 1" to the backspace of whatever everyone else runs for a particular wheel/tire combination. That usually means custom wheels if you want large tires. And at that point, you should just convert to BBP the right way with new brakes and axles.
