GNX style rims

[turbojitsu85]

I have aquired a 91 Pontiac Trans AM GTA that I will be getitng rid of because it is in such horrible shape. I am keeping the rims because they are the same honey comb style that are on the GNX or TTA. I have read some posts on here that these rims the back ones won' fit on a GN is there a spacer I can buy to make it fit or some other way about making it fit. I also want to make sure I am measuring the back spacing the right way as I know how to do it you take somthing and lay it across the back of the rim and measure down from the center. Am I right? Thanks for all the help and suggestions in advance.

There is a spacer for that application. Two come in a box, one for each wheel. I'm not sure of the P/N though. Alot of guys over here like to run the IROC and GTA rims on their Monte Carlos and Cutlass Supremes. I suspect you may need the same kind of spacer. When I worked at an auto parts store a few years back, we used to sell 'em like hotcakes.
