[QUOTE="Strokersace, post: 430517, member: 622"] OBS hose barbs on the bottom of the radiator are 5/16". They are removable on the plastic tanked radiators. Possibly so on the brass radiators but have never tried. I pulled one of the fittings and took it to the parts store to match up the thread and pitch for what threads into the rad. Then just get the 3/8" or 1/2" hose fitting on the other end. I've bought both at my local NAPA. I used some fuel/oil rated thread sealant for safe measure and have never had a problem. TARM, I've wondered if the 1/2" hardlines from a 5R100 6.0 would work? I've thought about it but have never investigated fully. The only other option is to custom make 1/2" line out of SS tubing. If either the 5R lines or custom lines would work the next item to address would be the fittings at the bypass tube on the side of the trans. It's possible, I just haven't investigated how to make it work as my 3/8" SD lines with 1/2" in and out of the radiator thru a 6.0 cooler has worked great. [/QUOTE]
