Jim, what is your kit for rerouting lines though the frame? I saw something that you have an idea or a kit. Idea from you would be appreciated, thank you!
I think you are referring to the transmission cooling lines. Brake lines already run very close to and inside the frame rails. Jim has a transmission cooling line kit to run push lok hose with AN fittings inside the frame rails
Lots of good info in this thread, https://www.v8buick.com/index.php?threads/transmission-cooler-recommendation.299758/ You can install these conversion fitting in the transmission case, https://www.summitracing.com/parts/sum-220027 and choose a cooler with -6AN fittings, and then it is just a matter of assembling some push lok hose and fittings.
Yep. I ran my cooling lines in the frame, use Russell Performance Twist-lok fittings and hose. Used red paint to "dot" the case, fittings, oil cooler and radiator connections for the pressure line, and left the return lines unpainted so I could keep the straight anytime I disconnect them.
