When we put the Dart together I had swapped the front perches upside down in it to lower the ride height too. The rear is a 65 B Body 8 3/4 that I mocked up to use for the 69 but it was just a little too wide. I just ordered the 002-003 but by the looks of things I'm not sure it matters a lot. Most of you guys in this thread are running faster than this ever will... Thx all...
