1968 Ford F-250 Additional Info:

Purchased the truck 1.5 year's ago. It was a farm truck before. Dings and dents, faded paint, but no serious rust, frame is straight, body mounts good. The bed is very rough, rotted in places, but usable. I've invested close to $4000 into it and it was my daily driver.
New:
C6 Transmission
Suspension bushings and Shocks
Brake Shoes, Hardware, Cylinders
Pertronix Electronic Ignition, Plugs, Wires
Holley 500CFM Carb
Fuel Tank, Pump, Lines and Filters
Water Pump, Coolant Hoses, Radiator
Optima Red Top Battery
All Lights work, Wipers Work.
Lots of little things.
Some spare parts, gaskets, filters, brake and carb stuff.
It has a strong engine, holds a steady 17lbs of vacuum. BUT right before the holidays it started running rough, loosing brake power. I replaced the brake booster, but now have NO BRAKES and it barely runs... Disappointing. I continue to troubleshoot, but have limited time because of work. If I solve the problem, the price will go up.
