TUBE SHOCK CONVERSION: If you would like to use the traditional coil/shock relationship but would like to switch to tube shocks, then these brackets are what you need. They are specially designed welded steel plates which are bolted to the frame in the rear wheel wells and allow the use of tubular shocks. You can choose in this case, the use of performance shocks like Koni or KYB and Monroe or Gabriel brands. They mount to the standard shock brackets on the rear differential support. Assembly of this system is very easy and can be done at any time during or after the restoration is complete.
