I just did a 129 rear to a 1250.. it was a little tuff for me being new to "tractor working" itself.. I also have like no tools.. very, very, limited to what I have.. And I made it work.. If you do move forward with a transplant,,.. Just look out for minor differences.. like rods and what not.. Ball joint to a rod fitting for your axle.. things like that.. I got a lot of good help from here.. Be very carful on removing your rear.. It will want to drop forward if you are not ready for it.. Don't know what you have to use, so BE CAREFUL!!

if it drops forward, than you bust up some things.. Look up "Broncocarl" on youtube.. you will see how bad it can be.. you don't want that to happen... Good luck with what ever you decide.
