The short answer is yes. Moser will cold cut and respline your axles for you. They say it's strong. But, if a rear axle brakes, then with C-clip your screwed. If you cut a front axle and it brakes, oh well, at least you can drive home. Secondly, I think you would have to switch to the larger F150 drums, which isn't a bad thing just costly.
New axles - $300US - $450 Can
Cut F150 axles - used axles $100/pair
- cut and respline $100/ per axle
=$300 - your not saving any money...
