Wondering if anyone has done this particular conversion, as the front lower bolt goes into a blind tapped hole, so not as easy as usual, can't just run a long bolt and spacers. The regular lower flange on the GM 1-wire I have is much too thick, but if I were to flip it upside down and drill the flange that is usually the adjuster side, and machine it a little thinner, it would line up, and just use a bolt and nut on the adjuster. As I also have a 330 with the same engine, wondering if anyone has found an alternator that will fit without mods- probably why I am not finding a kit for these particular tractors. PO of the 340 had installed a 12V bat at neg ground and ran it a long time, so it's generator is dead, Just pulled the one off the 330, which has a reman sticker, wishful thinking that it will work at original 6V pos ground, but would like to go to 12V alt instead. I see a few alts on ebay that came off 340s with some kinda hokey fabbed up brackets, trying to avoid that if possible
