Stupid question but look who it is comming from. I have no idea when it comes to big twin transmissions. I started to do research for one for my 49 Pan and have no idea what to look for. Last Pan/Shovel came with motor and trans and I didn't have to mess with it. I just don't want to buy something that I can't use or I will have to change all the parts over so it will work with my project. Last trans I did was on a pre unit Triumph and it took me a week to get everything right. That sucked!!!!! I have done a Evo Sporty and that was cake but never did a big twin. Can anyone tell me what I should look for? Don't need a case for electric start, kick only. What is the difference between years and the shaft? Mind you this is going in a VL frame w/ a 49 Pan. Would like to set it up with a 2 inch belt but I can figure that out, I think. Thank in advance and sorry for the stupid question.
