Gearbox mounting bolt sizes

[Bonzo]

Just popped in to catch up on some of the recent posts & noticed this

I have just had a look on my engine ( I used the original Zetec bolts )

They are M10 X 40mm set bolts ( Fully threaded bolts ) standard metric thread.

One difference over a standard M10 set bolt is that the head size is reduced to take a 13mm spanner .... I believe there is still enough room for a 17mm standard hex head though

If memory serves me right, 6 bolts will do the trick.

Hope that helps Dave
