After finding that with a rebuilt motor the previous owner had put a stuffed distributer back in with a 3 thou point gap, half working fuel pump and filter, etc, I have decided to keep the original engine and instead attempt to find a five sped box. Better to keep the old girl as close to original as possible after all she is 34 years old and still going well. All I really have to replace is the camper floor which is rotted. Other than that she is a great old girl
