Hello,

I am finishing up rebuilding a B18B1 for my Civic swap. I finished up the long block and putting on the accessories. I have one mount left, and I cannot for the life of me find where it belongs, or what it is for. It is number 9 on the diagram. What size bolts for it as well if possible.

Thanks in advance

 

It is a transmission stiffening bracket. The bolts that go into the block are 8mm x 1.25 pitch (12mm head)... I am unsure of the lengths off the top of my head, but the threaded end should stick out of the base of the bracket about 5/8" to 11/16". The single bolt that passes through the bracket and into the transmission is a 12mm x 1.25 pitch (maybe 1.50 pitch ???) (17mm head) and should stick out the back about an inch.

 

The lengths and sizes are all in the same parts fiche that you got the drawing from. They all should be 1.25 pitch.
