Default 8.5" or 9.5" Wheels?

I'm rebuilding an '84 and just discovered it has three 9.5" rims and one 8.5" rim. Stock was 8.5" front and 9.5" rear but this car has the Z51 suspension so I don't know if that changed the rim sizes.

My question is, which rim should I replace, an 8.5" for a 9.5" for stock setup or a 9.5" for the 8.5" for four 9.5" rims. The latter case would make tire rotations a lot easier. The tire size is stated as being the same for the 8.5" and 9.5" rims. Does that make sense?

Thanks,
Rick

I believe the Z51 gave you 9.5 all the way around.

1984 stock was 8.5,,, Z51 was 8.5/9.5
I recommend all 9.5s, unless you insist on being
factory correct.
84 silver

Both the 8.5 and 9.5 size wheels use the same 255/50vr16 tires.

Just for conformation. Base 1984's came with 4, 16 x 8.5" wheels. The Z51 option included 16 x 9.5" rear wheels, with the 16 x 8.5" fronts. The tires remained P255/50/R16's.

RACE ON!!!

THanks for the replies. I was leaning towards four 9.5" so that's what I'll do.
