I know the width of the frame rails changes from 3t to newer ones. But don't know which models, so take your tape measure. And if you don't mind some cutting and welding. The next thing to look at is the pump drive.
I had a 17A to sell some time ago, and from memory, the width of each machine was the same. Intended buyer wished to swap over from a 3T to 17A as well. Good luck. JM
