hello eric. congrats on the funk. i still have mine and am getting ready for a show next weekend. i'm thinking of taking my model 'A' pullford conversion and several hit ans miss engines, though.
maybe the casting number is "7HA" then it could be a 6010 or 6015 on the rest.
i am running 12v on my 6 cyl and v8 both. i had the generators changed over so they still look original and bolt up with the same brackets.
no way to oil the throw out bearing so you'll have to change it out when you break the tractor apart to silence it. i know of no peculiarities with mine. just have to remember i have an 85 or 95 hp engine with a 28hp rear end. LOL
if you need any other info let me know and i will try to help out. i haven't been on here lately, been busy on too many projects. LOL
later, will.
