Is it centered so they dont have to get custom shafts? How would you get the driveshaft to it?
If I remember correctly from previous threads talking about the axle in question, it was built to go into the rear of a truck to make it rear steer.
Regardless of what the axle shaft lengths are you still need to have custom inners made that have a yoke for the u-joint.
Back on the topic in general, I don't really understand why you would do this either. A bigger ring and pinion is all it gives you over a D60 which doesn't seem to be a common weak spot anyway.
Can't imagine it would be any cheaper than building a front D60. So a front D60 is going for $750-$1,000 while you can get a 14FF for $100-$200.
If you pay $1,000 for a D60 it should be complete and in good shape so bolt it in and go. Yeah, yeah, it's not a bling built axle but just saying you can have a functioning axle under the truck that is significantly stronger than stock with no additional cost for parts required.
Now take that $100 14FF and convert it to a front axle where you need to buy custom inner shafts, u-joints, outer shafts, inner C's, outer knuckles, spindles, wheel hub assemblies, bearings, locking hubs, brakes, spring mounts. Then perform custom machining and welding on the axle to put everything together.....all just to have a functioning axle. Add just the parts together and I'm sure you would easily exceed the extra $900 that just buying a complete D60 would have cost.
