76 Duster....Manifolds to Dual Downpipes

Well, they do fit tight and to the point all the way around the flange........I found a gasket online, but it's for the flange only, not an actual donut.

NOW, the passenger side pipe runs headlong into the oil filter......SO, I guess I'll have to install a relocation kit in there too..........doesn't look like a right angle adaptor will work either........looks like a relocation.

Any suggestions? You guys done this before on a Duster with manifolds?
