Does anyone have a set of sliding front suspension units please for the RH2B built with a sierra donor 2002. I have just stripped my two down as they both were grinding the inside of the wheels. Both SS inner rods were bent so I need them together with the units. I am going to upgrade the springs as well, if anybody has any of these two or ideas of what ones to fit please. The springs are obviously too weak they are red ones 22cm high x 6.5 cm diameter, no idea of the poundage nothing written on them. Suspect 180lb, going to try 250lb Faulkner race springs to stop the sliding ram from travelling too far, hence the bottom strut bolt grinding the wheel.
