Bought a prothane poly bush kit and have worked my way back fitting them as I go. Only two left are rear ones (according to the packet) they are like a thick washer about 2 inches across with two "ears" that stick up from the edge of the flat bit about 1.5 inches high. Now the rear beam is off and I can see the bush, they are not the same. Where do they go? The existing rear beam bush looks like a big meaty thing which I obviously need to look at changing. What do they look like and how much is this going to set me back
