    I actually just figured it out. I took some tin snips and cut it perpendicular to the clamp. It was so rotted that it just wittled through the clamp. I got it off and installed a new one. But I noticed something. That "rot" just peeled off. Underneath was a perfectly preserved hose. It looked like new. Weird. Now I want to know what that crust was. Anyone have some ideas?[​IMG][​IMG]

    There were speakers on the bottom of the door, but not factory. Someone cut a hole in the door and wired speakers to it. They didnt work so I took them out and were gonna replace them. The door pockets can be seen in the first post, I also removed those to replace the elastic. What makes you say they are from an 80? What do the original 78 ones look like?

    That's the old undercoating I mentioned in your other thread.

    Those oval cutouts in the door panels are for the '80-only optional front door speakers. There's a plastic speaker pod that would have mounted there. Map pockets were standard on the Cheyenne and Silverado style door panels, but there were no big oval holes behind them.

    I've never seen a filler hose crumble, they just get rock hard with age.

    There were different option groups for the Camper Special. Mine doesn't have the bed shocks, or the tie down points either. Just the camper harness, dual batteries and the steeper gearing. I think the original owner got the Camper Special just for the drivetrain stuff, because the camper harness has never been wired to anything. It's still bundled up and tucked in the frame, just how GM sent it.

    Interesting. Well I guess that makes me feel better about replacing them. They look awful and I wanted to try to restore them and keep them original, but if they aren't anyway that means I can just go buy new ones.

    Now I want to know the story behind this truck. The seller bought it from a woman whose husband died, but he said the tires were from the 80s. It had BFGs on one side and Power grip super wides on the other. One of them must be original and the other replaced. But my question is when did it sit? It must've sat a while because of the really bad sun damaged interior. The owner mustve had some time to take the speaker out of the dash, cut the hole in the door and wire speakers to the doors. I'm kinda curious if the dash is original too. It's not brown, but like some sort of red or pink color. If he took the old speaker out, he must've taken the dash off and maybe he replaced it. The other clue is that there was a small engine fire probably from someone pouring gas into the carb to start it. The hoodliner clip above the carb is melted and the valves in the air cleaner are too. Is there anyone that might know of a way to decode this things mystery?

    Thank you! I think I've fixed the hose debacle, so now on to other things. I noticed something else while I was under the truck though. The oil pan and transmission pan are soaked in either grease or oil. It concerned me a bit. I don't know if it's a terrible leak or just grease. Why would there be grease on the entire surface of the oil and trans pan? [​IMG][​IMG]

    The pans being covered like that is normal. Small leaks spread and collect, and that's what you get. It probably wouldn't hurt to do a drain and fill and change the filter on your transmission. Just don't over-torque the bolts. You could replace the pan gasket and timing cover gasket on the engine, along with valve cover gaskets to stop leaks, but a snugging-up of the bolts on the pan and timing cover and valve covers may just be enough. But those can't be over-torqued either. Even perfectly sealed engines will develop oil spots over time.

    Just slide the clamp up the hose and put the new clamp on when your new hose comes in then you can get all the old stuff out.:party36::grd:

    Before he cleaned off the hose, it looked like it would crumble. If you got the same type of clamp that came from the factory you'd have to slide the hose off of there, and that's what I was asking about. But if a regular clamp works, it makes the job much easier.

    Mine has holes in the front bumper but I'm not sure if they were drilled from the factory. They did have some heavy duty eye bolts in them though.

    Is it a bad idea to clean them off? It might look nicer. Is the grease there for a reason?

    It has collected over many years. Small amounts of oil leaks out, spreads around, dirt sticks to it and makes "grease" so to speak. You can clean them off. Doing so will help find where any leaks are coming from.

    Your dash is probably original, but sun faded. My '80 3+3 I had in the mid 90's was doing the same thing.

    I had a '79 K15 where the bottom side of the engine and trans looked the same. My truck had been parked for 5-6 at one point prior to me owning it. The valve cover gaskets were the cause of my problem. They were super dry and brittle.

    You were asking about when the truck sat. I know in California you can run a vehicle through Bureau of Automotive Repair's web site and see prior emissions tests. It can give you a window to when a vehicle sat or when it was sold. This is my old 1980 Crew Cab. I owned the truck in 1998 and the Registration was due at the end of April. I sold it to a friend in October 1999 and had to smog it. He owned it for a couple of years and sold it to another friend. It broke down and wasn't driven sometime between 2003-09 and again from 2009-14. It was tested again in April of 2018. Nice to know it's still on the road.

    Do you have the SPID label in the glovebox still? It might have been bought new without a radio and then aftermarket stuff installed soon after.

    I'm going to guess that the door panels were replaced soon before you bought it. If you notice, there's zero fading where the factory speaker pods used to be. Going off the pictures from before you bought it, the seller had other squarebody trucks too. There's a very good chance that the seller put those on because he had them and they were nicer. OR, it could have been the other way around. Maybe a lot of the interior was much nicer and the seller kept them for another truck.
