I did the same on my '53 210 but only 1 1/2 coils and 5" lowering blocks on the rear. I don't recommend much more than that. Don't put any "Gravitationally Challenged" people in the back seat or your drag plate will be literally draggin!!!! I'm now lookin' towards air ride, but lookin' seams to be the key word.

Ain't to proud to be broke down.
