Does anyone have the dimensions / specs for LA 318 oil pump mounting bolts?

no. but I have a couple extra sets of them from junk engines if you need a set of factory oil pump bolts.

you can have set if you want them.

I have lots of the case hard engine bolts. need any other bolts for engine?

1&3/8" shank/3/8" coarse & just under the head is a tapered/expanded shoulder like head bolts have. lightly snug the (2) bolts then install the intergear then torque the bolts to 35 & this aligns the hex interface dead on.

I do not have specs and a suggestion. Last time I needed OP bolts I went to ACE hardware after testing with a few bolts I had on hand. This for a non-stock HV pump. I picked what I needed based on length. At least 3/8" thread engagement and better 1/2". I used washers and mocked up w/o washer to make sure there was no bottoming.

I used grade 8 though grade 5 should be fine.
