With Dynatrac and Currie being a 4ish hour drive each way (for me, not all people can save on shipping) the possibility of a custom axle build has some merit. I might go that way if I do a 60 front. By the time I buy a 60 housing, gears locker, new bearings brakes and steering I am getting close to just buying a complete axle. I haven't priced it lately but last time I looked there wasn't much of a cost difference when all was added up.
I just checked Dynatrac and Currie's websites and pricing wasn't on either menu. Interestingly, Currie rear 60's are semi-float. Both companies seem geared towards providing primarily Jeep replacement axles.
I'm not down on custom axles, if I could afford one I'd do it but my budget doesn't work that way. Essentially, about 6 months a year I do fairly well, the other 6, well...
Hopefully in a few months I'll be the only one on the internet dumb enough to put a Dodge axle under the front of a Ranger. It has to get a van axle under the back first though. (I just reread those sentences and no, I'm not high. lol)
Man, I wish I had your fab skills, Matt.
