69 Camaro outer wheel tub replacement

[colorado80439]

Looks like I will be replacing the outer wheel well on my 69. We were replacing the quarter panel secondary to poor repair work from unknown trauma when we discovered the outer wheel well had been repaired poorly as well.
Looking to replace the outer wheel well with aftermarket, any experience, good or bad, with aftermarket sheet metal for this repair. I would do a GM part if I could find it
