Bellhousing options for Doug Nash 4+1
I've got one of them. I modified a factory bell housing to mount it up.
In the area of the factory bell where there is no support for a hole, I filled in with a chunk of aluminum and weld, set the bell housing up on a milling machine and fly cut the face smooth, bored the register hole out to fit the retainer.
Send me your e-mail and I can send you some pics.
