8 3/4 rebuild issues

Thank you in advance for any and all help. Well I was putting 8 3/4 clutch pack back together and when I was bolting the 2 half’s together one of the case bolts broke. So I need to know if anyone knows where I can get these bolts.

i believe ARP has them -- 3/8 -24 FINE left hand thread -- McMaster - Carr only has left hand 3/8 - 16 coarse thread -- if you cannot locate a bolt ( good luck ) and do not want to spend what ARP wants for them -- take a spare ring gear bolt cut off the head and get a regular grade 8 bolt the right length and cut and weld the two together for the correct length,, if welded properly it will take the torque required.
