The 1979 and 1978 Full size Broncos are beasts. Solid front axles make them very easy to lift..... but also make them very easy to abuse off road. Most of them I see look as though they have been rode hard and beat on repeatedly through the years... ( not many of them became mall crawlers). I absolutely love the look of them. I have no idea what skill set you are bringing to the table. Are you an experienced fabricator or just an enthusiast starting out? If you are skilled fabricator and have no problem tearing down transfer cases and re gearing your differentials then I would say the 1978 and 1979 are a very solid platform. If you are just starting out... and will be figuring all this out of the fly.... or heaven forbid actually paying someone else to repair/ upgrade your project.... then I would recommend a 1996 Bronco to start with. You can find some that have not been beat on, have relatively low miles (160,000 or less), and the 1996 has OBII and the mass air flow upgrade.. along with a 3G alternator. I see really great examples of these around Atlanta for the 6k price range. If you live in the great white North look into buying a rust free Bronco from Arizona or out west. You cannot pull and replace rust..... and this is BY FAR GOING TO COST YOU THE MOST to have someone else repair. I have had this obsession going on 15 years so i want to see you get something that you can enjoy.... and fall in love with. Once a project starts sitting around and not being driven for a while.... the fun disappears quickly.
1979 parts are going to suck... since they only made that model for one year. It doesn't sound like you are dropping 10,000 on a really well maintained Bronco. Any vehicle produced in 1979 is not going to have the nicest road manners.....especially if it has been beat on.
