What Am I Doing Wrong????

Thank you Rameth for seeing what I said. Again,the entire driveline,engine,trans,rear end is shifted to the right. Dont know the exact amount,but it is.

And PLEASE dont cut the perches off your A-body axle !

Something to keep in mind,there is a little difference between 7.25 & 8.75 A-body axel measurements. However this slight difference has never stopped them from being a direct "bolt-in" procedure.

A=Backing plate to backing plate B=Spring perch to Spring perch
A B
1963-1972 7.25 53.200" 43.02"
1973-1976 7.25 51.400" 43.02"
All A-body 8.75 51.400" 43.00"

As you can see the 8.75 is actually .02 narrower than the 7.25
