Rear End Bushings

[ponyetr]

OK, maybe I'm being a moron here, but I got some new poly bushings and tool from Gbodyparts the other day. Along with the bushings came some rubber rings, one thicker than the other. The stock bushings did not have these. Do I use them or not?

Yes you use them. Unlike stock type rubber bushings the rubber is bonded to steel so they remain self centered. Poly bushings are floating so without the spacers so there is potential for metal to metal contact. All the bushings are the same but the bushings on the top of the axle housing use the wider spacers.
