Slow, but steady... I made the decision that I'm going to install the 261 that I picked up. Along with the 261 I'm moving forward with it's matching sm420. I found a PTO and test fitted it today. Everything looked good. I probably won't do the swap for a while, but I wanted the plan and parts in place for when I'm ready. I'll figure out the trans mount and driveshaft length differences when the time comes. I don't see that being much of an issue.
