Why To Never Buy Chinese Sh*t

I bought a set from Mancini when I rebuilt my 360 2 years ago. I had 2 break when I first installed them. Called Mancini and then they tell me they are made in china. They let me return them for a cam. The needle bearins on those are junk so even if you do find adjusters (I never did) they will break. If you have to have adjustable on a budget like I was use 273 or cranes ductile iron ones.
