First and only set of MS seat brackets I ever saw for sale was through Rupewrecht... (I bought them of course) He still has 1 set to make copies from but has yet to do so. If enough of us bother him and he could get a committed list I'm sure he would get them produced. I want 2 more sets...
He is the mazdaspeed man
I hit him up about it, a little while back, he said he was at some stage going to do copies, I'll have to shoot him another msg about it, see if we can get the ball rolling
