My version of a inner fender support/front subframe stiffener

I think its a waste of time messing with this shock mount! The weight of the car is soley on the k-frame, torsion bars and their mounts. It would be much easier to cut a piece of 3/16 plate and box the shock mount in and gusset the top portion. As long as you leave the radiator support attached to the front of the frame rail there will be NO twist in it. The frame rails are High Strength Steel. If you go welding on it you will end up destroying its strength! I know its a crude drawing but you get the idea! Weld up the sides and plug weld along the frame rail to keep the heat down. Leave enough room to access the camber bolt nuts.
Then add the factory braces from the firewall to the inner fender apron.

To many folks believe that the "SHOCK MOUNT" is a part of the structure! All it does is is support the shock during jounce and rebound! Thats it!
