 | 700r4 I lost both my mount bolts and i need to know what size bolts they are. Napa and advance auto parts both have told me that they do not know the size of the bolts. Anyone have a clue what size they are or where i could find out? I brought a new mount and of course it didn't come with the new bolts. |

 | I think they are 7/16's but cannot remember exactly. Take the mount with you to a napa or something and test fit some. or do you mean the bolts that mount it to the tranny?

| Ok guys, I went outside, climbed under the 57, and removed one bolt so I could verify the size. It is not the same as the bellhousing, it is metric. M10X1.5x30 That is 10 mm x 1.5 thread x 30mm long with a (1/2") 13 mm head. Somebody owes 75K30 a cold adult beverage......... |
