Bell Housing to Engine Block bolt length

Do any of your shade treee mechanics out there know length of the bolts that secure the bell housing to the engine block? I know the thread size is 3/8 -16. Are they 1 1/4" bolts or 1 1/2" bolts? I need to get my hands on some

I've always used 1.5" if I don't have the originals. I never have measured the original bolts, so I can't say what they are, but I can say what works.
