Kook,If you roll over on the other violaters,the moderators will find you safe haven in the Stovebolt witness protection program.A new identity as a FoMoCo owner and a job as a liberal union activitist will cover your trail.

Actually ,the sites you mention are on the links page ,so you're with in the spirit of the "law" lol
Yes, the swap you mention is good and simple. When I was looking for a 4.10 pumpkin, all the ones I found were hammmered, bad bearings, and pitted gears.I never had the luck to find a good one.The cost of new bearings plus a $400 3.90 ring and pinion set had me headed for the barf bag.Hated to drop a wad of cash into an old rear axle for a work truck.So the rugged 14 bolt became an option.My situation was for a 68 C20, which is sold now.I had a 49 GMC 3/4 ton a while back, with a 14 bolt full floater from a 75 Chevy pu. The axle is on the wide side for good looks but the truck is a beater, and the 3.73 made for less stressed cruising.Good used 14 bolt axles are $200-$300 around here.So maybe the guys above will let us know how they make out.
