I sure wouldn't want to try to mount the flywheel sensors on an
engine that didn't have them originally.  They have to be pretty close
to the flywheel teeth.

On my car, the distributor would be out since it's driven off the
camshaft which is belt driven... too much slop in the system.

I don't however know how I'd front mount anything on my car either...
