Welded differentials.....who is willing to admit that they have done it?

True story.....
I installed a mini spool into a factory cone style sure grip unit over 20 years ago....
I believe I machined 1/8” off of the cones(the side where the spring plate is) and the mini spool fit. I might have machined the cones for the mini spools axle splines to be “located” too... IIRC
Perhaps beer induced but it worked!
Mini spools were designed for “open” rears and were only $29.... lol
