there used to be a company advertising all the conversion stuff for morries,like torana brakes & a series engine & gearbox mounts in street machine magazine,but this is years ago,& i don't know if that company still exists.the rta now wants these cars to use toyota 4a's,to keep the emissions down,or some such excuse.so somebody out there must know what bits to use.there was even a morris minor in historics with full mg running gear,was a bit of a shell.try the street machine association in your home state,they might have somebody with a car you could look at.just a warning,these are now considered classics,so the price of even a wreck would be lots.
