Looks like you have a bigblock in there?
I don't think I would rely on the stock stamped shock mount to hold the weight of the entire front end of your car! That factory washer is just gonna shove through the shock mount. The mount is too thin to support that much weight.
If it were my decision I would rebuild the mount totally with thicker gauge steel altogether.
This is why Alterktion has its own coilover mount intergrated!
I think in theory it was a good idea but this mount was never intended on holding the entire weight of the cars front-end. Too many folks believe that this is a structural part, its not! All it does is support the shock during jounce and rebound. The K-frame, lower control arms, torsion bars and their mounts hold the weight.
Take it or leave it but that is my 2 cents. This coming from a I-car Gold trained/ASE Master Body tech which specialized in structural repair on uni-body cars.
