396 alternator bracket to intake bolt thread size

[Jack O.]

Hi,Can someone please tell me the thread size of the bolt that attaches the alternator bracket to the intake on a 396/425 engine. I need to repair one and I can't tell exactly what it was to begin with but believe its a 5/16 course?.Thanks!Jack

Jack,
If memory serves me right, it is 3/8" - 16 (USS) According to the AIM, it is the same bolt as used on the lower bracket. See sheet A3.

Yup, it's 3/8-16. The bolt was 1" in length.
