All I was saying is that Gates is talking crap when it came to the spring. The late design they make may be fine, better looking than what they sold before.
Don't know anything about the Dorman and probably will not find out. Dorman has made so many absolutely horrible quality parts that I avoid them whenever possible. I used to have to warranty everything they sold. The three bolt thing just so they can most likely make one part serve in more than one application, you just wouldn't use one bolt position there. Lifetime warranty there means nothing at all, they make parts so cheap they actually plan on giving you more than one. A very cynical way of bringing you into the worthless parts fold, if you will. They don't care if you have to yank the part 5 times.
