UCA bushings

I need to replace the upper control arm bushings on this rear end i just removed. Is there a special tool? I need to order the Hotchkis bushings to fit the arms i have. He used them, so i don't have any bushings.

you should use the stock rubber on the upper rearend
or are you changing the bushings on the control arms?
Control Arm Bushing Tool This Bushing Tool (Part #0599) is designed to remove AND install the bushings into the top ears on the rearend housing. This tool is made to fit GM housings, and may fit others as well. The design includes a roller bearing thrust washer for ease of use and long life. The Bushing Tool is also plated for rust prevention and appearance. The Tool PULLS the bushing out and also PULLS it into the ears, and does this in under 2 minutes with an air ratchet. Ask anyone that has done this the hard way, and they will tell you this tool is a life saver. Hours of aggravation can be avoided with this new tool. Some generic pullers with adapters to fit (hopefully) your application are over $400! Our tool is designed specifically to work on GM rearend housings for sure, and possibly others as well.

The stock ones are pretty beat, the hotchkis bars are brand new, I want to replace the ones on the rear end. The hotchkis arm kit come with them, but the guy I bought them from used them already.

the hotchkis arms should be poly they go in easier then rubber ones.the rear end ones you can hit out
with a 2lb hammer then make a tool with some treaded rod and some steel flat bar to install them

I'll try to pound them out, if worse comes to worse I'll use them, it was driven hard, the frame mount holes are elongated bad, it pays to use the right bolts!!!
