Which company offered P/E inserts for the original AMT '57 Chevy's rear fenders?

These were P/E pieces that were meant to be a significant upgrade over the kit's rear fender decals.  

Anyone install them on one of those old AMT '57 Chevys?  Got pics?

The Model Car Garage set is designed to fit the original AMT '57 kit.  I bought the kit to use other items on an old Revell kit, and the MCG quarter panel trim wouldn't fit that kit so I didn't use it.  It should fit the AMT kit just fine though.  I'd avoid putting any paint on that area if you intend to use the P/E trim.
