Rear Lower Trail arms 97 4x4
So I picked up a set of brand new lower trail arms for my expy at the wreckers while I was getting my Torsion bar. The donor was a eddie bauer just like mine, same year, both dont have air ride. The torsion bar fit great but lower trail arms have a different bolt size and are a bit longer.. Anyone know why this might be?? I watched them take the arms off so I know it didnt come from another truck. Im Confused. Any help would be appreciated.
