Sorry, Mike I was looking to see if there was any difference in how wide the bellhousing's are for the 22r's! They mount in the same holes, but I was looking to see if any were slightly larger in diameter! Or are they all the same!
I've gone to that post, it's all about length. Not width!
The reason I was asking, is the exhaust manifold and downtubes I was given (big open chamber for the 20r) was supposed to work on my truck, but the down pipes hit the bellhousing, crossmember, and the torsion bar mount, and won't let me get close to the mounting flange of the ex. manifold! Well, I got the other (header style 22r) exhaust manifold and the downpipe still doesn't work. But to come to find out, was the twin tube downtube I was given won't work, I need the single downtube!
But I would like to know if all the bellhousings are all the same diameter? That was my curiousity!
