@JP - they are on the Evo rails with EP feet welded on. Other than a quick lick of hammerite on the welds, and a cheeky look to see if i can mount the crutch straps to the sub frame, they will pop straight in and be fully compatible with the Willans harnesses. That was the whole point of these. One of my existing rails died a while back, and whilst looking at solutions, I didnt want to end up with some new seats and no means of fitting them as I don't have the contact to make up universal rails that I had originally a few years back. That's why I was looking for GT seats for so long, as they would (mostly) pop in. There was a set of Evo Recaros popped up for sale over here, but again, no means of installing them. The beauty of Wallace's set, apart from their mint condition, is the fact I don't have to spend further time and money buying rails and finding someone to construct them. I dont have regular contact with my original mechanic any longer unfortunately as he was the chap who did ALOT of my early work, even fitting handbrake covers, as daft as that sounds lol. Cheers Wallace dude, excited isnt the word! been investigating methods of delivery from the brother's house already lol. Phil.
