I am sorry, but a non running 30 year old vehicle that is suspected to have a blown head gasket as the cause of it being a non running vehicle is a parts vehicle. and worth at the most 800 bucks, and that is if everything else is good.
There is not much pics of the body of the truck either, in fact you do not see any of the passenger side. paint looks to be in poor shape, altho being a California vehicle, rust is probably not a factor. but what does the passenger side look like? did a bus scrape it off? interior looks ratty but may just need a cleaning. Mileage on the odometer for this year of truck does not mean much either, as it only had a 5 place odometer. could be 87,671 miles or 487,671 miles.
800. tops and that is only if the passenger side of the truck is undamaged..
