That should teach me to do my research
I'd heard that the GT500 strut mounts were a big upgrade over the stock GT ones... so I bought a set from a private seller... nothing wrong with them, they're in good shape, but guess what? They're identical to the ones I already have. As it turns out, from 07 and up ford already put in the upgraded GT500 mounts. Same part number and everything.
So... anyone with an 05 or 06 want to upgrade their strut mounts?
