Morris Minor Owners Club

i have a smooth gearbox that came out of a 59 minor it has had new bearings and was running fine when it jammed coming from 1st to2nd gear i took off the side cover moved the selector and was fine again it then got jammed again after about 50 miles so decided to fit a different box in the car, it could be an easy fix as it did run well,theres also a box with gearbox internal parts which comes with the gearbox i only want £30 for the lot, also a radiator from the same car which was not loosing water when taken of and was given a good flush out £30 for that or £50 for the lot
