Most of the truck vendors sell the Factory Assembly Manual ($29.95). I ordered mine from Brothers, when I ordered the pass side cab corner patch panel. When I get back to the SF Bay Area next week, I'll take some pix of the ebrake system and post them. It takes very little effort to set the ebrake handle which holds the truck easily on my steep driveway while setting the timing and dwell. My truck like yours has a 250 inline six. What's weird is someone must have installed a 292 oil pan, when they installed the 250, because it hold six quarts of oil.
