Is there any point that a pack reaches where it’s not worth getting re arched? If the steel has just degraded to the point it won’t retain the new arch for very long?
something not frequently talked about (but mentioned in this thread) is torsion bars. What about replacing torsion bars due to sagging? I believe there was different bars even within the same year/model range, let alone different capacity levels. How do you pick the right ones? Or can they easily be re sprung?
i believe there is a code on the torsion bars and that’s what you’ll use to order new ones. I couldn’t imagine what would be involved for fixing torsion bars since they get twisted. Maybe some fancy cryo treatment like crankshafts.
