So your rev counter works? That is so much easier!

As for the cross member.. 12v 2.9 was slapped in mk3 Granada's as well as mk2 Sierra's, in fact the mk3 Granada and both mk1 & 2 Sierra's shared many engine and gearbox arrangements, and as such I would reckon that Ford only made as many engine cross members as they had to.

The BOA & BOB are based on the 2.9 12v Cologne block, not saying the actual arms between the block and cross member are identical , but I am referring to the cross member on its own.

All I can say that I 100% know for fact is the way I did it.
