I have a 1958 Ferguson tractor with a continental engine and Delco ignition. It is dificult and expensive to replace ignition parts. I am looking for a 4 cylinder distributor to adapt to my tractor. Tractors like Massey Ferguson's use the same delco points as on Chevy 4 and 6 cyl. engines. I was thinking of using a distributor from a Chevy Vega / Monza engine or perhaps a Volkswagon. It needs to be a common engine with a small distributor cap. If anyone has such a distributor contact me ghausner@mail2george.com Thanks
