Finally got it installed...was not a 20 minute install. I had to take some meat off the arms with eye holes because they would not clear the uni-drive. So it's gonna need a little paint, but I like it!! 😊
I am sure there will be other more qualified people that will chime in on the subject, but both of the 312-8s that I have did the same thing. A $15 rebuild kit fixed them both, the magnum and the k series. Good luck, and welcome.
