Thanks for the responses.
Smokeycub, you mentioned a link in your post but I didn't see one...
gitractorman: Thanks for the links. I didn't see a discussion on swapping front ends, but the diagrams were helpful. I can't weld, so I am looking for a bolt-on solution. Which is an easier axle swap: Part # 759-3270 (for 129, 149, 1250, 1450, etc.) or Part # 759-3271 (for 984, 1572, 1914, etc.)?
Are the axle pivot pin holes the same diameter on narrow and wide frames?
Thanks
