Oil Cooler attach bolt length?

Does anyone know off hand what the standard length bolts come in the baffle kit to attach the oil cooler to the engine baffle. My baffle is cracked and I'm going to reinforce it with a .63 angle. So I will need longer bolts.

Thanks,

Baffle mounted on my -8...I know with the oil cooler shutter door it uses AN3-42A 3/16 3 7/8 long. And I believe AN3A 3/16 3 3/8 without the shutter. I did the reinforcement and used 4 1/8? This assumes you are bolting through both mounting tabs and bushing between.
Watch the lower inside bolt that it does not contact cylinder 4 fins.
I ordered a selection from ACS to find the best fit and still used a couple washers on the mentioned lower inside.
