The price wasn’t bad, but when I got it the quality and condition wasn’t that desirable. It fit in the truck and does it’s job, so far, without any issues. Time will tell though.

Good replacement
Fits exactly like stock! Only problem I had was one of the trans cooler fittings leaking but some Teflon tape fixed that! Be sure you tighten the fittings before putting the radiator in!
