I need to install brake lines, MC, and prop. valve. Help!

I guess my most pressing issue is I don't know what size of tubing to buy for the brake lines. What size is the line on the '73+ calipers?

Should be the 3/16th (I think that is the size); basically standard size brake line available pre-bent from places like Fine Lines; or in sections from the parts stores or in 25 foot rolls.

In Line Tube has an atrocious web site. Might be good stuff, but really hard to navigate their site.

I am debating bending my own line, or going pre-fab. Problem with Prefab is that they may not line up with the new MC and I'd have to hack on them for the new rear axle.

For the rear axle, maybe Fine Lines or In Line Tube will have pre-bent lines for your 8.8 w/disc brakes application. They might even have lines from the M/C to the proportioning valve.
