Long bed brake line location

[ab_70chevy]

Iv got a '70 long bed C10. Turns out the connection between the line that runs from front to the rear and the hose to the junction block is pretty well corroded and is just seaping out. My question is, where is the union on the line at the front? My truck is pretty low, and I did not have a chance to get it on jack stands and crawl under it. Im thinking I would like to get some straight lines and bend them myself until I can save up enough cash to buy some nice stainless ones.
Id appreciate any help
Thanks fellas

Fellow wichitan!!!! The first union is under the prop valve on the inside of the frame than the rear head to the passanger side behind the front cross member than it heads to the rear, there is also a coupling under the passenger door area that connects the front hard line to the rear to the bed rear hard line. Check out lmc trucks and veiw there online catalog and type in brake lines it will give you a good picture
