What would you do, 340 Dart?

if you get a 9" ford you will have to shorten, remount spring perchs and a few other mods.

Look for a B or C body 8 3/4 best to get 742 case 3rd member, do the mods to it then use all Mopar Parts to do brakes

300 HP doesn't need a bullit proof rear end

Whatever you do if it isn't an A body rearend it will cost for the mods, what is better? or cheaper?

I know a guy that has an Abody rear at one point said he would give it to me. I ask him about buying it later and he said "I think I'll keep it". It is laying in his backyard in the dirt. You would have to meet this guy. He is very talented and could build anything he wants. But mainly talks alot and does nothing. His 74 Dart Sport is also sitting in his back yard rotting. he said he wants to make a tube frame to put under it, (yes he could, but the car will never see the road again) His dogs (BIG SHEPARDS) has gotten on it and dented the top down, broke the rear glass, so this car is turning back into the earth one day at a time.
