Little update. I was able to go to a diesel shop and get a proper banjo fitting, it was also $4 cheaper. I tried to get out the studs on the manifold but 3 out of 4 snapped. I guess I should have let them soak longer. But I did get an idea where I can just leave them as is broken in the manifold. Seeing that Id have to use two gaskets on the flange with a spacer and longer studs I decided to just weld the flange on. I can tap the spacer for new studs which will be the same as the original as far as length, I can use whatever thread I want, 1.25 or 1.5. I will have maintained the single gasket configuration like original and I wont have to remove the old studs which are proving to be a huge pain, Id probably need to drill them out completely if I needed to get them out.
Also got my pulley back. Turned out it was only $10! It looks pretty good, looks like a single row pulley.. haha I called a guy in town about getting the spacer cut but he hasnt called me back.. Id really like to get the turbo mounted within the next week or so.
