i need to bolt the rubber mount back to the transmission, that also bolts to the crossmember, does anyone know what size the bolt it? I found that a turbo 30 uses a 7/16"-14 bolt.
but i couldnt find anything for the 700R4!

 

btt

 

metric, but not sure what size.

 

if Im not mistaken I think the bolts that bolt the crossmember to the car have the same threads Id take one out and see if it will thread in and if it does Id take it to a hardware store and get one like it and as strong as you can get so it holds up to the pressure that it has to.

 

It's 10mm x 1.25mm I think. 10mm diameter for sure, and whatever the "standard" (not fine) metric thread is for a 10mm bolt.

 

your right, it was the same as the one that holds the crossmember to the sub-frame.
