SUCCESSFUL F1 SHOCK MOUNT RELOCATION in P15-D24 Forum Posted July 7 · Report reply I don't know the shock mount length I used, but I will say I'm still using my original length shocks. Sometime back, some people said they used longer shocks. They gave me the model numbers so I bought a pair and discovered they were too long....hit bottom real quick. Tried re-using originals and they seem to do ok. Could probably use a shock one inch longer actually. Hope this info will help some.
