Good evening all I am looking for some advice if possible I have just got a replacement seat for my car as the seat base bolster was starting to fail. 
 

I got a seat that looked really good in the picture but think it might be from an accident damaged car as the bolt holes in the floor don’t line up properly. Both the front ones do and the rear left one line up ok but the rear right one is out by about 10mm if you pull the seat runner you can get the bolt in but when seated it feels like your slightly facing to the right. Has anyone else removed there seats and had this issue on re fitting them or has anyone stripped down a seat as I was thinking worst case removing the cushions and covers from the replacement seat and fitting them to my original frame. Can anyone tell me how you get the seat base cushion from the seat base frame. 
 

thanks steve 

Sorry, I have tried. If the bolts are off then get a refund, I don't see why there should be a difference.
