bellhousing and fuel lines 74 k10

[black&gray74]

Hi my 1st post ever and cool sight
Rebuilding 74 k10 to k20 how does the return line run or did I get a 2 wheel drive line my old lines all went around the rear front shackle hanger together and the new one does not have the same bends (3/8 fuel and brake line), saw pics where there is a line going along top of the front cross member also looks like to steering gear and now I am just lost (2 outs sending unit tank and one on fuel pump other goes to carb was edlbrock)
Sm465 bellhousing is cracked 3 or more spots and thought of get one from classic industry any ideas of other places to buy
Got to run check back later and gets some pics
