WHO sells the best A-Body strut rod bushings?
if you go poly, and they're too thick (likely) you can freeze them and cut them with a hacksaw or a ban saw (if you're done cutting pistons).
unless you've got other trick components up front, staying with rubber is the best course of action on a stock or nearly stock front end.
fwiw, i just ordered and installed two sets of moogs. one set went on a client's car about a month ago and i installed the other pair on my project last night. both sets were made in USA and the quality looked good to my calibrated eyeball. maybe i lucked out.
if you're looking for another source try mevotech supreme MK7040. i use a lot of mevotech stuff and it's generally good to great quality.
i'll echo what the others have said up thread: if the strut rod bushings are waxed, chances are other stuff is borked as well. double check you LCA bushings, you'll be there anyway to do the struts.
