If you are using a radiator from our friends at TAPP in Sophia, NC (which we recommend highly...call Russell and tell him Scoutco sent you!)...you can bet that these cooler lines will bolt right on with no problem. All the fittings you need to go from the transmission to these braided stainless Teflon cooler lines, then from the lines to the radiator's built in transmission cooler ports, is ALL right here in this kit. You get two 90 degree fittings for the top end, and the fittings to go from the AN lines to the GM automatic transmission, as well as the high quality lines themselves...which are not some cheap-o lines that are screwed together with the hopes of them holding up, but these are Teflon lined flexible braided stainless steel with crimped on fittings, able to hold up to a LOT more pressure than your transmission's pump will put out. Overbuilt...juuuuuuuuuust right!
