I would send them back to CHINA were they most likely came from and try to find a set of N.O.S or an original supplier such as MOOG at a auto parts store. I have found several old stock MOOG parts left at the old mom & pop auto parts stores ( the very few that are left) or E-BAY. I bought a set of repop strut rod bushings from N.P.D and they were not even close to correct and half the weight. I was able to buy a old MOOG set that at the time was still all U.S.A made and they were almost exactly like the original and some things I felt were even better. I remember before all the so called discount chains came to town, you could by a quality OE supplier part at the local auto parts store and you would get OEM quality because they were the ones making the parts for FORD, such as BENDIX, KELSEY HAYES, MOOG, WAGNER etc..Now most of these company's are either out of business or have plants in MEXICO or CHINA to compete with the inferior lower price parts. Sorry, I am rambling but that's is a big problem in this hobby is dealing with import junk.
