I've heard--and it makes sense--that healthy Power-Lock diffs in the rear axle make it more difficult to steer a stock FC on pavement. I suspect that stepping up to a Dana 60 w/ Power-Lock would steer even worse. And, the Dana 60's larger brake shoe area will cause serious tire skidding unless you have a very heavy load in the bed or add a proportioning valve...
You didn't ask about it, but some people REALLY want 4 tires in the back of a flat bed. The Dana 70's are VERY heavy duty, but serious overkill for FC150's. Road worthy examples of the ORIGINAL 70 are getting scarce considering nobody retails new ring & pinion gears w/ the correct offset(that I know of)... I COMPLETELY rebuilt/ restored my DRW, except for the diff in the rear--bearings & backlash weren't bad.
Anyway, spring perch width, brake bleed screw access, open or Power-Lock diff, gear ratio, drive shaft yoke/ u-joint specs, shock mount locations and brake power are just some of the considerations when swapping axles.
Just my 2 cents worth...
: The 170 DRW used a Dana 70. Does the 60 have
: the wheel bolt pattern you want?
