Hooker 5901's & Summit Exhaust into my '67 Dart

Just installed my Summit Small Block Universal headers, it fit my 73 manual steering/power brake setup without any hammering. Lots of swearing at the #5 bolts on both sides and the #3 bolt on the passenger side, no clearance between tube and bolt head, period. No way to get a box end on it. Just a sixth of a turn, flip wrench, four ninths of a turn, flip wrench, have back spasm, etc. But they went on real nice, had to pull the fan/distributor/lower radiator hose, dropped steering link and used my hoist to lift the engine up. If I had a buddy I could have done it with a floor jack, and probably a lot faster than it took me alone (3 hours or so). I got the Summit Exhaust collector reducers installed (hopefully sealed), then I laid in the squelching mud and got ichor on me and I called it quits for the day, but it looks like it mates up with their Dual kit pretty well. The drivers side tubes hang down low but they'll probably be fine.

It's been a while since I've looked at a P/S box but I don't think that it'd fit. The header is close to the coupler, the main body in two places, and the mounting ears. Who knows though, with hammers, much is possible.
