Brake line question
 

Howdy, Okay dumb question. What size is the hard lines on a 1987 Chevy Suburban 1/2 ton 4x4 ? Also..what size is the brake line nut and is it standard or metic.

What I am doing is putting a Chevy 4x4 drivetrain under a 1964 International Pickup. I need to pickup brake lines and start bending.

Thanks in advance for your help.

There are 2 different size coming off the master cylinder, but it looks like all the wheels use the same size.

Idiot proof
 

The different size fittings are so the correct ports are connected to the distribution block, correct chambers in the M/cyl to correct lines to front and back. I try to keep the M /cyl , lines and dist block all to gether and tag where front and rear hook upwhen doing a swap.
