Default Re: '65 GMC 1500 project. From the Netherlands

Pulled the old Dana 60 today. Went pretty smoothly. Broke off one of the U-bolts, see picture. I'll tell ya, when you're laying under the truck without hearing protection and you're breaking them loose using a big pipe and a wrench, these make a nice bang when they snap!

Glad I took it all apart, the lower axle retainers gathered a lot of crud and were corroding the U-bolts. I am planning to drill out the drain holes to 1/2" or so instead of 5/16". New U-bolts will be installed

Got a new Spicer 29 spline yoke to fit the new gear set. Planning to take the whole axle apart and clean everything up, then start with the regear process. I'll use the old bearings as setup bearings, found a nice article describing the whole regear process. It takes a little patience to do it properly but in the end, the result makes it all worthwhile. Should allow me to do 60 comfortably instead of straining the engine. Usually drive around 55 anyways.
