I measured the distance from the adaptor to the flywheel and
it was within a couple thousandths of an inch (very close) to
where it sat originally. They make these adaptors very well.
After this is completed you can put the whole
motor/transmission system back in the vehicle with the
hoist. Remember to have your helper there to guide the
process for safety.
It is not difficult but at times it can be awkward, needing 3
hands at times so ask your helper for assistance at this point
for convenience and safety.
Depending on which vehicle you choose to do your
conversion on will determine how easy this process is.
