Bolting Gearbox to Vangaurd

[Tony R]

I need to bolt a gearbox to a 16hp vangaurd. Can someone tell me what size bolts I will need to thread into the engine? Thank you

3/8" X 1 1/4" - 1 1/2" coarse thread with a flat washer and lock washer.

Make sure the bolt isn't too long. You can punch a hole in the engine block if it bottoms out and you tighten it down.
