1984 GMC 3500 Sierra Classic 3+3,4 door,crew cab,HD, 4x4

I have a 1984 GMC 3500 Sierra Classic 3+3, -door, rew Cab, D, X4. The truck has normal rust areas for this year. The truck runs great, arries 40 psi oil pressure and drives really good. Geared low, o many have to be hauled depending on how far off you live, t has A/C, .7 V8, riginal Dana 60 front, urbo 400 Trans, 05 transfer case, ual tanks, 35/85/16 Radials with over 1/2 tread. This truck is tagged and titled, t alsohas a new Virginia inspection sticker. It has always had a camper top an bed liner on it. The bad. it has a newer exhaust but a small leak on the passenger side(doughnut) gasket area. Tanks switch great left to right, ut when you fill the one up on the drivers side it has a slow leak. This is a very good truck and I hate to get rid of it, il has been changed regularly, t shifts good and is not beat up. Feel free to ask any questions, 'll answer the best I can.
*The current odometer reads 23,145 miles. When it was put in the old one read 80,000 miles.

* After some questions on "normal rust" for this year I posted a picture from under the truck. In my opinion ( I'm NOT a professional mechanic ) it needs a good sand blasting and undercoating, hat had been my plan before I decided to sell it.
