The rear suspension knuckle bushings in my 93 Eldorado ETC are shot. Other than a set of Honda bushings that fit in the knuckle by fluke, you cannot buy replacement Cadillac bushings. My question is: is there a huge difference between the rear suspension set up of a 93 ETC compared to later model ETC's? From what i can tell, they're more less the same from 93-98....It looks like I'll be scavenging wrecking yards for replacement parts as new are pretty expensive. Wear wise, I'd be better off buying knuckles of the newest model possible. Any info is appreciated!

Cheers!
