Original GM Casting #547975 Bellhousing
This is a good used Buick, Olds and Pontiac clutch housing. It is nearly identical to the GM casting 9785581.
With this particular aluminum housing, I have chased the four 1/2" transmission mounting holes (not pretty but will hold). There are some scuffs in the transmission bearing retainer hole that might need dressing.
There are no cracks or repairs.
This is a limited stock item. Pictures and description are of actual part.
