This may have been covered before but I haven't seen a specific thread with pictures so here you go...
After looking around for 1996 C4 Corvette front wheel hubs I found they were quite expensive. Anywho, in the depths of the interwebz I found a thread about using Fbody hubs on a C4. To note I don't know if they work on any other models other than 91-96 C4 and more specifically I am only knowledgeable on the 96.
The only real difference is the Fbody hub bolt holes are threaded. Another note is I am not running ABS, so I can't make a claim on whether the reluctor ring has the same teeth or if the plug is identical. I'm just some guy that happened to buy some 2002 Fbody Moog front wheel bearing hubs and install them.
My car is a 1963 Grand Sport with a C4 suspension and a lot of other custom goodies. Im running 315/30/18s up front and 335/30/18s in the rear, so if the bearings are crap I will find out real quick.
