Are the seats the same (frame, padding, shape, etc.) - just different covers between these car seats? ie: Will the GT500 Recaro seat covers work on the Boss 302 seats? I'm of mind to switch to leather and save the originals for my kid when he gets the car someday. I have 12,000 miles on my car, and my cloth Recaro seat covers aren't gonna be worth spit in another 12,000. Really disappointed in how these are failing to hold up. Figure leather gives me a fighting chance. Just don't want to order the GT500 seat covers if they don't fit the Boss seats - but in photos, they look the same. Any opinions or expert analysis out there?
