4.0l Oil Pump Bolt Sizes

I lost the bolts that mount the oil pump to my 4.0l block. does anybody know what size bolts they are? I tried looking in a parts diagram but no luck.

Long bolt is .312-18x2.625", also needs a flat washer and a lock washer.

Short bolt is .312-18x1.00", also needs a flat washer only.

Suggest Grade 8 hardware.

Edit: For the 2.625" (2-5/8") to may have to buy a (5/16-18) 2-3/4" or 3" bolt and cut it down to 2-5/8" OAL from under the head. 1" bolts should be a common stock item at the hardware stores.
