Cars looking good
Tried to do the same as you and put a zetec engine and mt75 box together using a 1.8 flywheel and Mondeo clutch, you either need to extend the pivot point or extend the release bearing neither which work very well, best is to drill the flywheel for a pinto clutch or buy a flywheel designed for the job
The sump can be made or use the 1.8 sierra one, the problem is the oil pickup pipe that has to be the correct shape, the 1.8 sierra one does not seem to fit very well in a blacktop engine
I would recommend buying the correct conversion parts from retro-ford, I now have and should have done so at the beginning saving a lot of time and hassle
Good luck
