Wow, what a blast from the past. Those Ractive seats are the exact ones I used in my 83 buildup 7 years ago...same color combo too. Very easy to make fit. The seats lasted great. I drove the car with those seats for over 2 years as my daily and no tears/rips and comfy too. Just a little fading on the upper bolsters.
Not to hijack (and I think I posted this somewhere on this board), but here's my old cardomain page:
