Quick question

I think (I may be wrong) that the 2" drop spindles are only available for the larger balljoints on the later (and Large Bolt Pattern) 73-73 A bodies. Which means new upper control arms, lower balljoints, and brake hardware. I think you will find doing that swap is the best anyway, because you will have trouble finding wheels in the size you want in the 5 on 4" pattern on our earlier A's. You may also look into new rear leafsprings instead instead of blocks. They can be purchased in stock height, or 2" lower from several companies. Good Luck getting that Dart in the dirt.
