I've seen the ones for the round gauge SS cars but I was wondering if anyone makes a repro sweep style dash for a '70-'72 model? And if so can it be ordered radio delete?

No reproduction sweep dashes. Round style only...

The best advice is to check the salvage yards in your area that specialize in the older cars. Look at the four door cars. They are usually in better shape. I've found two dashes in the past couple of years that were in excellent condition and both came from four door cars. I'm guessing that the original owners were older and they kept their cars in better shape.

Use the wanted adds on this site. A lot of guys are swapping out the sweep dash for SS round. Should be able to get a nice one for a decent price.
