Funny you should bring this up...I have your answers.

- trouble with the swap-
1. the upper control arm ears are too far forward and too wide apart
2. shock mounts are in front of the axle tubes instead of behind on the the g-body and 65-72 a-body
3. the 73-77 is 4" wider than your stock g-body diff easy.
4. not sure about the sping perches even being in the correct spot left to right either.
5. drive shaft mods will also need to be done since the 8.5 has a longer pinion then the 7.5 rear.

Problem solvers:
1. I have now had manufacturered sets of upper control arm (fully adjustable) this will take care of upper control arm situation. No Problem.
2. do already build complete housing using the 73-77 center section and narrow and mate the other brackets to the rear creating a bolt in rear for your G-body car.

Upper control arms are for sale for 150.00 a pair. they will solve that problem. If you are willing to do the rest then there you go.

If you want a housing it is 350.00 with axles it is 579.00 .

A whole rear built will be about 1000.00 with all new parts. not including the upper control arms.

This is still way cheaper than Moser Housings.
