a really nice bellhousing from a 1967 GTO 389 4 speed car. all the holes are good, and I see no cracks. part number 9785582 this bell housing was used in Buick Oldsmobile and Pontiac cars from 1964 F85, 1965-1978,hence the starter mounting on both sides. these were used with the GM 4 speed transmissions, or also had a second bolt pattern to fit the Ford (Dearborn built) transmissions.
