74 Dart w/ 340 6 pack

So I got her back and I've put about 500 miles on the new transmission.
The difference is night and day and the way it shifts I see lots of black lines in my future :burnout:
Also I am thinking of moving my rear shock brackets down because the rear end moves around like a belly dancer. I do like the rake of the car but I think I'm going to try to lower it 1-2" in the rear just above the rear rim.

I'll take a couple of pics before and after and see what you guys think.
