Treblig's doughnut?

Hey, I've ditched my headers and installed some 1971-1972 exhaust manifolds on my '65 Barracuda with a 360.

The passenger side is casting number 3618623 and fits fine. The center dumps looks reasonably straight forward to access in order to make a head pipe. The driver side casting is 3614368-2 and also fits fine, barely missing the steering column, but it's in there. The dump points slightly forward so it needs a head pipe or adapter with a pretty sharp 180 bend. I've seen Treblig's nice donut that solves this problem but don't know what to do about getting one. I think I read he doesn't make them anymore on another thread?

Tried to message Treblig but his inbox is full. Treblig, are you out there?

Did anyone buy one they're not using? I brought my car to a good exhaust guy and he basically told me to get lost. Maybe buy a huge Buick like he has to make it easier on myself next time. Ugh. Not what I need.

Thanks,
