I'm doing the S10 frame swap with a 42 pick up. I thinking about moving the tank to the back and using the 4DR Blazer tank. I've read posts on this forum and the S10 forum, and it's been done. I'm wondering if instead of going the wide side between the frame rails, if it's possible to rotate it and have the filler tube facing the rear, instead of the side. It would give more room for dual exhaust. Has anyone tried this? It looks like it'll work.
