Outer Limits 4x4 Board

I am looking for some replacement seats for my 82 SWB MQ, the fronts and foldable rear 2 seater. Can GQ seats be put in or what, and what about other model nissans like the skylines and stuff? I dont really want to have to go modifying rails etc and would like to have the front seats still foldable and slidable.

Cheers

Can be bought to bolt directly to the stock rails. These are what I am putting in my 83 MQ.

i didnt want to get aftermarket ones though cause i dont want to spend much money. just want something cheap to replace them.
