Perhaps someone who is better versed in fitment of wheels can tell me if this wheel will "fit" the 124 Spider. Look at the Dorman 939-248 wheel specs and you'll see that it's remarkably close to original specifications for the 124 with the exception of a single mm in each direction of bolt pattern and a single mm larger wheel bore. I believe the 40mm offset would be acceptable. Please chime in as this can be a solution to a real problem, not to mention the specialty price if you can even find FIAT aftermarket wheels.

It seems that the 1mm makes all the difference in the world! I doubt that this'll work. Besides, the necessary adapter would add stresses that are certainly not optimal.
