Need Bolt sizes for Thermostat Housing and Water Pump Pulley

[Chythar]

I don't know what happened to the originals, they're gone. Probably best to get replacements anyway. If someone has these sizes, thanks. If you know of an ARP kit that fits, even better.

Thanks for the help.

I think the heads were 1/2 on the water pump pulley so the threads are 5/16-18 and the length is likely 3/4". I cannot recall the thermostat bolts but I am assuming 5/16-18 again.

Anybody got an aftermarket bolt brand part number for those asked about? (t-stat bolts and water pump pulley bolts)?
