Seat rails

[Neu Alt]

Was looking at a Malaga 74 2002 yesterday that is a pretty good solid project car. Was able to check most of it but being close to a wall I couldn't get a good look at the seat rails. I would need to get the seat back further for my
6-3+ height. Was able to do it on an E21 a couple of years ago (with seatbelt extender brackets) but am not familiar with the 2002.

What's involved? Has stock tan interior.

The seat rails are riveted solid to the base. You cans use a seat base from any 96-05 https://hashing24.com/i/banner/7/7-2-2.jpg (https://hashing24.com/?rid=53616c7465645f5fee7ea2d8981f2e744682e7e7036c0 197)
