Well if the numbers are correct it should take ACDELCO 45G9092 for the front A arm rear bushings and ACDELCO 45G9090 for the front A arm front bushings.
Here are the listed dimensions.

45G9092 -
Length 2.76 IN
Inside Diameter 0.570 IN
Outside Diameter 1.670 in

45G9090 -
Length 2.60 IN
Inside Diameter 0.660 in
Outside Diameter 1.900 in

GM used the same parts on many cars BUT they changed part numbers a lot. What I did was use a couple after market part numbers that fir the car, then crossed those to newer numbers. If you measure up the old ones it should tell you if they fit.

Those are the numbers for the lower front A arm. There are 2 different bushings, one goes in the front of the arm the other in the back.
