You can install cooler lines on the vehicle right?. I don't know, doesn't seem hard to me. I ran tubing for years as an EI&C tech. I'll find you a couple more pictures to ease the mind.
Fabricating lines is not difficult. Possessing experience makes it much easier. Since the SS lines that mikiesride is using are prefab, I suggest it would be best to wait until the engine and transmission are in place and then massage them exactly for a perfect visual and functional fit at that time rather than fret prematurely.
Hopefully all will be needed is small tweaks here and there. These Inline Tube lines are "supposedly Pre Bent" for the application what ever that is. But on the other hand like every thing else on the Market these days for Restoration Parts they need to be "Massaged" some.
It is becoming progressively rarer to find anything that fits and functions
as it should right out of the box. True quality and precision of manufacture these days are little more than a dusty memory.
