I did take 5 inj that I pulled out of a junkyard into a mom and pop diesel shop(
http://www.dieselandimport.com/) here in the metro. they tested them for me, all were good. they wouldn't even take my money.
a while later I needed a few heat sheilds, as 2/5 of the ones from autohauzaz didnt seal, and they only charged me $4 for 3 of them- cheeeper than anywhere else I know of.
needless to say, they now have my business(if I ever get in over my head)
