I just bought a 79 3/4 4X4 I found in a barn. The fan alt. and belts are off of it and there is a new water pump on the truck. The problem is the long bracket bolt is broken off in the head! how do I get it out without haveing to pull the head and take it to a shop?

If it's broken off flush with the block try an easyout. It's a tool that looks like a twisted punch with a square end on it. You drill a whole in the end of the bolt. Stick the easyout in it. Put a wrench on the end of the easyout and start turning. The edges of the easyout dig in to the whole you drilled and hopefully it turns the bolt.
Good luck

Another tip I read about for bolts broken flush in cast iron. A fellow claims that a welder could weld on a stainless rod to the end of the broken bolt to give you something to grip with vice-grips. The helpful part is that the stainless won't stick to the cast iron in the welding process. You may still have to tow it to a welding shop or have a "house call", but that may be cheaper and/or easier than pulling a head.

Sometimes the simplest way is the easiest. Try spraying some liquid wrench on the bolt and then twisting it out with a screwdriver. If that doesnt work use a reverse drill bit and a reversible drill. This will usually back it out unless there is a lot of rust, corrosion, or the bolt is crossthreaded. In this event you will need to use the easy out that someone else mentioned. I also like the welding idea, I may use that myself sometime.
