'69 Barracuda T56 swap, floor, cross member
Set up dial indicator and took measurements with the .007" offsets at the 4 o'clock position which is where they were when I had that aluminum bell housing (first picture). With the steel bell housing it was out of alignment. Ended up with .007" offsets at the 7 o'clock position and that allowed runout to be within specs (second picture). I removed bell housing and reinstalled and measurements did not change.
Note I am using 3/8" studs in the top three holes (second picture) because I was not able to get my hand up there to get bolts in without cross threading. Studs are 3/8"-16 2" long from McMaster-Carr rated at 150,000 psi tensile strength. Nuts and washers 3/8" grade 8. I am also using grade 8 flanged bolts on the two lower holes. Quick Time provides allen head bolts and no way could I fit an allen socket up there so that hardware wasn't used.
