porsche tombstone seat fitting

Hi folks, probably an age old question but i just bought a pair of 924 front tombstones for the cabby. I assume they wont just fit straight in (that woild be too easy). Can anyone give me an idea of what i will need to make them fit? Can i use subframes from seats i have? Do i need special ones?

these are my old porsche seats, i got them with the mounts already fitted, they sat very low :mrgreen:

Cheers for that ans4r, i will have to think of a way of raising them a bit too

To make the job simple, a pair of cobra tailored subframes may help if you have the runners with the porsche seats.

You can re drill and modify these to fit other seats.

I used a pair to fit the Alfa seats into my cabby, simple process, just needed to add an extra cross bar on to them.

Are there such thing as bolt on kits for these seats? I dont want to remove the existing runners on my car as I might want to put back in the original seats at some point.
