I think I have wrong rear seat - help

Did the seat fit before you took the stuff to have the upholstery done. If so, I think you upholstery shop may have covered the wrong rear seat & gave it back to you. I would contact the shop & see if they have another customer whose back seat doesn't fit.
No, I thought I had mentioned that in my post. Interior was done and new except for the old nasty seat so I didn't want to put it in but knew it was the seat that was in the car when I bought it. I got the same seat back I just never checked it prior. I found some pictures in the forum classifieds I'm just gong to fabricate some bottom reinforcements and replace the tall ones this seat has. It should work, I hope haha
