I have a 1990 GMC K2500 with the 350 engine in it. I have a radiator from a 1990 with 6.2 diesel that I want to use as an upgrade. I have everything to install except hoses to connect to the 350's smaller piping. Has anybody done this upgrade before or know what hoses I could use to connect. I can go to Napa and search their hoses for ones but that's a hit and miss till I find one.
