I've recently purchased a pair of front 67 chevelle shock absorbers. I'm in the early stage of a frame-up on my 67 SS and the engine is out of the frame, therefore the suspension is fully extended. However when attempting to mount the shocks, I'm unable to attach the nut to the top of the shock stem, because the stem doesn't extend far enough to protrude through the frame. Ofcourse if there was enough weight on the frame to collapse the suspension some, I would be able to get the rubber bushing, washer and nut on. That means that when the suspension unloads during operating conditions, the suspension will try to pull the shock apart. Would anyone know the proper fully extended length of front shocks for a 67 Chevelle?
