I dont know if this is gonna help but both my 67 swb trucks have a threaded line coupler/union behind the front c member allmost in line with the firewall
from that fitting to the 90* bend in the rear it is 90" with the bend where the rear rubber line connects looks too be another 2".

My stepper has the oe line, my swb fleet we replaced it with a hand bent line so its a little more wavy. but from the same fitting to the rear it's still 90 1/2 but like mentioned the bend for the rear rubber line is about 2 more inches

hope you get this figured out
