Hello all,
Am currently in the midst of a frame-off restoration of my 1970 Series IIa. The original front pipe was toast, so I got an aftermarket one that does not seem to want to fit the original exhaust manifold very well. After much manipulation, this (image below) seems to be the furthest that the rounded proximal end of the front pipe will insert into the exhaust manifold output. Any thoughts or ideas? It almost looks like there needs to be another gasket here but there is not one listed in the Green Bible, Haynes manual, 2a parts catalog, or series 3 parts catalog. Thanks in advance.

And for those wondering ,yes, I struggled mightily to get the 3 original manifold studs out...so many broken drill bits.
