62 dual path transmission converter bolt set

Hi need help PLEASE!!
I have a 62 special with the Daul path 2 speed. My converter bolts (3) loosened up, almost worked there way out. I am looking for a new set. ARP does not seem to offer them. No luck on summitt, jegs, fastenal, napa, rockauto, or two local trans shops. They are Black Chromemoly 5/16 x 1.250. A grade 8 bolt has been suggested but chromemoly has a higher tensile strength and I am told a A3 thread tolerance vr a standard A2. The bolts go into an original threaded aluminum housing which probably has a loosened threads as the bolts were torqued down and walked themselves out after a 2000 mile rebuild. Where can I buy a 3 bolt set of converter bolts? Lots of 7/16, 3/8 and 10mm.
thanks
