Anyone fitted Corbeau seats?

I had a pair of Corbeau Forza Sports in my MK1 Golf and found them very comfortable while holding you firmly in place, I was hoping to put a pair in my 90 but I'm not sure how to go about fitting them, I ordered a pair of subframes for the Golf but they don't do any for the Landy. Anyone got experience of fitting these or similar?

i fitted a pair of rover 220 coupe leather recaros in me 90..just made up 2 rear brackets and drilled two ne holes for the front fixings piece o ****,most things can be made to fit a landy thats the great thing about em and why we love em
