How hard is it to switch out center caps, say from the gt4 wheels from AmericanMuscle. I aslo saw a guy on here had cool centercaps that said GT in red, anyone know where to get those?

 

I think this was discussed at length a long time ago.

I took a set of stock caps, sanded the back flat, and epoxied them onto the plexiglass centers from DD wheels from American Muscle /Mustang Tuning. Some sandpaper, a little elbow grease, and two part epoxy and it was done.

Worked perfectly.
