Switching those loaders to QA is challenging because of the way the dimensions work out. And then the bucket either needs to be converted or replaced. You would be better off switching to a QA bucket because they are taller for the attaching parts. Converting the pin on bucket ends up with adding risers for the hooks.
We have a nearly completed design in the works to make the transition to Deere QA for the 60, 70 70A loaders, but it is unclear how much of a demand there is for it at this point so it hasn't been finished up.
