whell mine are going and i am wondering where everyone has gotten theirs and for how much.. i was looking at the pettit ones but they are kind of pricey

 

If you want solid diff bushings I'd put a want add in the third gen for sale section. I sold solid Delrin diff bushings for $100 shipped but I'm sold out right now. If you are interested in Polyurethane, Rob (Wanklin) is doing a group buy for Super Pro bushings and has the diff bushings available separately. Check the Group Buy section for more details on both products. Good luck on whatever you choose.
