D60 axle perch question

[Jeremed]

So I finally decided to put a kingpin Dana 60 under my YJ. I am going to leave it sprung over for now. The leaf springs are within 1/4" of fitting on the stock spring perches so I will be fine with the width. Just wondering if anyone has ever cut that piece that is molded into the differential and put a different spring perch on so you could change the driveline angle. It would be easy enough to cut the top piece and grind it down, but the bottom piece where the u bolt would go around is another story. I have heard of people notching that to fit a u bolt into it. Just not quite sure I am ready to hack away at that. Thanks for your input.

Try a wedge on the spring pack, make sure to change the center pin bolt on the spring. Another option is to cut and rotate the inner C's.

Chevy/Dodge or Ford 60 (if Ford what year range)? I'm guessing early Ford.

I would never cut into the main web, especially the lower web, if it's at all avoidable. If I picture what you're up to correctly, I would drill a hole through the web, right against the "tube" area, so your U-bolt cant be where it needs to be, and install the U-bolt through the hole and then rotate it to the correct orientation. That way the integrity of the web is pretty well maintained.

It is a Chevy kingpin. That might be an idea to just drill a hole in the web. I bought some 6 degree shims. Probably just going to go that route. I have heard of people breakin those bolts off in the axle housing that holds the top plate on.

I'd say castor is likely more important than your driveline angle. I bet the factory caster is 6 or 8 and you put shims in to fix your drive shaft and it might track real badly if you don't rotate the c's too. Mine's a lot different 60 setup than yours but same issue. I had a cv front where the yoke pointed straight at my tcase, now I need a non cv shaft and will go that way if I start having issues other than the vibrations.

it will absolutely mess you up if you rotate the entire housing like that-- stock caster on a GM axle is 6* if I remember, or 8, Steve and I are on the same page heh. Rotating the housing up will reduce caster angle, and make driving very interesting...
