Small Bolt Pattern Wheel Adapters???

I'm using the TransDapt cast spacers on the rear of my Dart. Of course I only have a very slightly warmed 318 with a 7-1/4 rear end. I figure the rear will go before the spacers.

The thing to watch for with any spacer is the thickness. These TransDapts are 1" thick (typical) so I really had to work at it to get 215 tires on 7" rims to fit. I had to remove the wheelwell trim and roll the fender lip up. I still get some rub even now with a heavy load. Your Duster may be different though.
