Does anybody here know where I can get a 5/8" (16mm) thick T25, 4 bolt flange? I’m having a clearnce issue and need something to use as a spacer. I’d also be interested in a 1/2" (13mm) thick b18a exhaust manifold flange for a similar issue. I’ve searched the net but I’m getting dick-all for results and the shops around here are completly useless in accomodating what I need.
