What size bolts do I need to mount my frame mounts to the frame? These are the mounts for the motor.

I don't know thw exact size but you should buy Grade 8 for the strength. I think they are 4in

No, the 4in are for the engine to mount to the mounts. Maybe someone else will chime in on the exact length. Do buy grade 8 tho.

1" will work and probably close to the stock length. I used 1 1/4"

3/8's ;)

3/8" x 16

I put grade 8 bolts in the spot you are talking about, an hour ago. I used 3/8" by 1.25". Perfect length if your gonna use a flat and lock washer, they are a bit ch to get in though. Have fun. graemlins/thumbsup.gif

I tapped the holes for 7/16" fine thread, then I ran the bolts up through the frame bottom side, finished them off with lock nuts and lock washers.

Probably overkill, but I like overkill :D
