D60/14 bolt corp diff cover bolt size

[darwink1]

Im looking for the specs for the bolts that hold the stock differential covers on. Id need the size, thread pitch, and length. If I had access to the damn van Id just remove one of each and head to the bolt place but since I cant.....

Axles are from an early 80's chevy 1 ton.

Also, if anyone has installed aftermarket covers, ruff stuff in particular (flange is just under 3/8" thick), did you need longer bolts?

Thanks

3/8 NC If I am not mistaken. Your length will vary if you are mounting brake pumbing etc.
