didn't they change the phoenix to a FWD around '79, like the citation?

if the one in the field is a RWD, they will fit. if it is a FWD, i dont think they will, but seeing as it has rally IIs, it is likely a RWD. i saw some rally IIs on a mid-size bonneville (the little bonneville) from the 80's, and i had no doubt they would fit.

the f-bodies used the same bolt pattern all along, even the 4th gen, i think. my 87 RWD cutlass still had the same old 4 3/4 pattern too, as do the S10s to this day.

i think you are thinking of the FWD cars, Q. you can use rims from a vette, an s10, or any of the mid size RWD cars from the 80s & 90s. as long as they are GM. (i dont know about the C5). actually, i dont think they made any mid size RWD GM cars in the 90's besides the f-body and the 'vette, did they?

they did change the full size pickup bolt pattern sometime in the 90's though. but those never fit us anyway, i dont think.
