Having recently got my truck on the road i'm finding the original seat has excessive bounce,it's like a full scale game of Buckaroo in the cab!
I noticed when the seat frame was stripped it originally had burlap/hessian 'dampers' in the springs,these obviously were well rotted out after 60+years.
Do any of you have any suggestions on a cure,as trying to replicate the original set up would be tricky if not dang near impossible.(for me at least)
