1984 Custom Deluxe Short Bed Blue & Cream 350

This truck has had a lot of money invested in it; the vin number indicates that it came with a v6 but a 350 v8 has been dropped in it with an Edelbrock high rise intake and Edelbrock 4 barrel carburetor (which runs kinda rich, believe) with chrome valve covers and air filter top. She's got true dual exhaust and headers. (Headers look rusty) She's had a blue metal flake and solid cream paint job, one the entire interior in blue and cream (blue carpet, ash, eadliner, lue and cream vinyl seat.), nstalled 4 10" audiopipe subwoofers behind the seat, nstalled an engine kill switch under the dash, ad an electric sunroof professionally installed (does NOT leak: I can run water over the top to prove it). There is LineX spray-in bed liner in the bed and under all 4 fender wells to prevent rusting. There are no fluid leaks (oil, ater, rake fluid, ct.) anywhere. Last month, had it serviced at R&B automotive, local auto shop where they checked it's timing, eplaced the valve cover seals, erviced the brakes, rake fluid reservoir, hanged the plugs and plug wires, ir filter, ct. (I have the receipts.)
The body is super straight. There is no bondo, ust or dents on the body, ust little dings (from acorns??? Maybe) here and there but they're near impossible to see in person and even more inpossible to see in pictures. I also had the speedometer replaced since it hasn't worked since I purchased the truck in 2013. The battery is about a year old and the tires are in excellent shape.
I've also had the original sliding back glass replaced with a solid back glass to keep the rain and potential burglars out. (I still have the original sliding glass window if you want it.)It has manual crank windows and manual locks, he heat and the factory a/c works great. The air blows mostly from the bottom vent for some reason. Never had it looked at. There are some areas in the interior that reveals this truck's original color (brown.) the seat belts and buckles are still brown (drivers side seat belt has a couple of stains on it.)1. Dome light doesn't work,2. Cruise control doesn't work3. Horn doesn't work4. Analog clock on the dash doesn't work.
