Brake and Fuel line sizes for 1960 GMC 910 Fleetside long box?

[Legend56BC]

I finally retired from racing my stock car and have started to help my daughter with her 1960 GMC 1/2T Fleetside long box with 261 in line 6 and have a few questions. The brake lines and fuel line that came off the truck are just butchered up junk people have replace over the years so I want to get the correct lines sizes for both.Is the rear 2 lines that go with a stock rear end 3/16" line?Is the long line down the passenger side 1/4" line?Is the fuel line going from tank to 6 cyl fuel pump 5/16" line?I would like to use SS line and in BC here there is a company that pre bends to factory specs,just waiting on price before we order or wee will go the do it your self route if it is costly.Thanks for responses in advance.This is for this truck below.
