slant six bellhousing pattern

Also seperate bellhousings are always for manual trannys. The most common automatic for a slant is a slant 6 904, or it's variants (but NOT from a smallblock V-8 which won't fit) and the bellhousings are an intergal part of the auto's (one piece). There was also a 727 for the slant found mostly in trucks and vans, but I haven't seen one in a long time. There are different hole sizes in the back of the manual bells for different trannys. I don't know those sizes but someone here might.
