I've had rubber hose on mine for about 5 years and only had one accident where one popped off. Now it is double clamped. I would love to upgrade though. Any pics of this Oreilly brand line? Also, did GM make a pre-bent line that will fit a half-ton upgraded to the 34" radiator?

 

I used my stock lines and they worked out fine with my 34" rad...although I already have an auxilary trans cooler so my top (return) line no longer goes to the rad, but to a hose to the cooler, and I have a fitting where the factory line used to go. From what I remember though, the trans cooler lines mount in the same locations as the 28" rad. The bottom (feed) line bolted/popped right in without any modification
