I know many will say I overstuffed my tubes but I fit 7MM wires along with the coil wire through my tubes. (My coil is mounted on my firewall) I used Vaseline and pulled with an electrical wire that I fed through with a long zip tie. I also ran my temp sending wires through the front of engine and back to other side to clean up the looks of the engine. Most of this was after thought and the first four wires per tube where fairly easy, my plug wires were not cut to length and came without ends and gave me the option to turn the wires so all the ends looked the same and the manufacture writing is in the same spot on each one.
I went through a lot of trouble for this small detail and not one person has ever noticed yet!
Thanks Walt, I keep saying I'm gonna put the hood on, but I like the looks off. I just hope the paint don't fade and the hood won't match. I used brake lines for my fuel, I didn't want the same looks as alot of folks who bought theres from vendors. I cut and threaded my throttle linkage to look stock too. No one has noticed yet.
