Hello first post so I hope this comes out alright... 

We have an Allis Chalmers ACP50 fork lift with the G-427 (Continental TM27) engine.

Started skipping then wouldn't start, found that water got into the distributor and the drain holes were plugged with dirt. There's no tag on the machine with a serial number to indicate the year and there's also no tag on the distributor. I'm thinking it's a prestolite but I must not be looking in the right place because I haven't been able to find something that looks exactly the same to be able to look up replacement parts if they're even still available. Are there parts still available for these old machines or am I looking at buying a new distributor that I see are still made by Pertronix for the Continental TM27. Thank you in advance for any help!
