Sub-frame/ engine cradle replacement question

[Myotis1134]

Ok, got the sub-frame from Wasilla, going to clean it up- maybe POR-15 it. Does anyone know if there is a write up on the bushings? I'd like to stick some polyurethane in there, as the vibration-transfer shouldn't translate too badly, and the added stiffness should be an improvement. I just want the size of the bushings, otherwise I'll just measure off of the good side.

 

I've browsed the stickies for poly-bushings, but they all seem to be for suspension.

As far as I know, no one makes poly bushings for our engine cradle. I would just use regular brand new ones, I dont think theres very many options here.

yeah presently our only option is new rubber ones. I have the gm part numbers listed in the parts number thread

Just to let everyone know, NAPA started carrying these as well. part # 650-4111

right on. so rubber for now, possibly use the new rubber ones as a mold for polys.
