Trying to solve the eating up of rear u-joints

T-case Yoke measures at 5 degrees

Rear axle yoke measures at 12 degrees

allow one degree for axle torque

6 degree shim needed

Am I figuring this right???

Replace the perches, they will double as an anti-wrap device. Of course you already know that because I have told you. If you insist on using shims use these http://www.rubiconexpress.com/Products.aspx?Cn=169&Pn=1751&XnPath=169&Vid=0320B46701257 and replace the center pins with these "you will most likely have to drill out the springs" http://www.rubiconexpress.com/Products.aspx?Cn=169&Pn=1758&XnPath=169&Vid=0320B46701257


Or you can do like I said and get these http://www.ruffstuffspecialties.com/catalog/stupid-strong-spring-perches-p-181.html make sure you get the correct width.

Replacing the perches is something I am planning on doing at a later time. Don't have a welder right now and just blew my toys funds on a built center chunk and axle shafts

For the time being as far as the pinion angle, have to roll with what I have at MY disposal to work with.

Been looking at these from wild horses

Hoping my math is right.

You might want to take advantage of this offer, I'll help you weld them back on.

The ones I have are 2.5" wide. You can have them (laser cut from 1/4" plate and CNC formed). I just need to borrow a trailer again for moving the buggy to my new house, wink wink...

I'll just need it to load up the buggy and move it to the new house, about 3 days or so during the week

I've got the steel to build one, just haven't had the time to do it yet...

so, would the 2.5" spring perches work for you? I'd think it would be close enough..

Triple check that measurement Ed, there are some 2.25" springs but 2.5" is far more common.
