RE: DISCbrakes on a 50
I am running the stock I beam solid axle. I've upgraded to 4 wheel powers discs, front and rear sway bars, changed to an open driveline with a 1980 Camaro 10 bolt, front monoleafs, and rear Dodge Caravan multileafs. Front shocks are high pressure nitrogen, rear are 1/2 ton truck with custom mounts. I've also move the gas tank under the bed. I am currently looking into possibly having the axle dropped a bit, as I would reaaly like to go a little lower in the front. I have 16 x 8 Corvette style rally rims. It has a 261 inline 6 that I want to add headers and dual carbs to, and a granny low 4 speed. I also converted it to 12 volts, added a radio, and rewired most of it. In the process of insulating and carpeting, as well as replacing the glass, etc. It has been a long project, mostly due to money, but very fun. I love to drive it and get many looks and positive comments wherever I go. The end goal is to have a safe, reliable truck, that I can drive whenever, and wherever I feel like going.
P.S. Decide what you want out of the truck first. Driver? Hauler? Cruiser? Hot rod?
That will help decide the suspension, etc. Rebuilt stock suspension works fine for a cruiser, but if you want to go more than 55-60 mph, or lower it to the ground, you will need some modifications. Just remember, once you chop it up, it is hard to put back together. Like another member says, there are a ton of crappy, half finished projects out there for sale cheap. Don't make their mistakes.
Hope this helps.....Mike
