These pics are the first day I had the truck on 6-25-2006 when I unburied it and got it out of its garage grave.  It'd been sitting about 12 years.  only had 76k on it.

1st pic is it in its resting place...lol

rest are when I drug it it out, aired up the tires and got it running again.  surprisingly I just pumped a bunch of r-134a into the ac system and it worked for another 3-4 years.

Oldest pics I have of the truck.

1st is Grandmother and my sister on a road trip in 1981.  Not sure where.  I was 1 then...lol

2nd is a Trip Grandad to Wyoming in 1982 to go hunting and such for a month.  He had this framed in his mancave room.  His truck with the camper (no trailer) is at the far top right.  Grandad only used the camper shell and didn't take the airstream unless grandmother came with him.

3nd is Grandmother and Grandad Visiting Sanborn IA in 1983.  Grandad usually had that camper shell on it with the airstream.  the airstream is parked at the campsite so they're driving around in the truck.

4rd is me in 1986.  5 years old in IA the airstream with the old truck in the background

5th is my Grandmother, Nell in IA in 1986

6th is me and my sister by the Pocahontas statue in Sioux City, IA in 1986.  Truck with camper and airstream in background.


On the Iowa trip when I was 5 me and mom and my sister made the trip in the back of the truck in the beds in there.

Build Sheet and such.  On the build sheet the Engine is a TDS.  no one knows what that is, even the experts.  any clue guys?  been trying to find that out for 20 years.  Also the original Cruise control instruction card that hung on the turn signal lever when new.

I do still have the dealer Emblem for Jerry Brown Chevrolet that came on the tailgate.

It IS a Scottsdale.  When I restored it you couldn't get Scottsdale Emblems so easy but Silverado's were readily available, especially with a 20 on them so I went with Silverado.  It Is a Z62 Scottsdale truck though.

On 6-25-2026 I'll have had my 78 C20 for 20 years.  Grandad special ordered it new.  You older guys remember me because I posted all my restoration stuff on here while I was doing it.  Unfortunately my big build thread got wrecked when photobucket went to pay only.  Oh well.  Photobucket broke half of the internet.

Well I'm gonna make this a likely long thread.  As I get time I'm going to post a pictorial history of my truck, both before I had it until today.  I'm gonna upload a lot of old pics that are likely gone from my build thread.  All this is my celebration of having my C20 for 20 years.  I'll never have another truck unless something should happen to this one.  I have it just like I want it.  I don't need anything more.

So first set of pics is first day I had it in 2006 vs i think 5 years later...  Enjoy yall!

General Discussion / Truck Toolbox Divider

« Last post by 78 Chevyrado on June 14, 2026, 08:11:40 pm »

Was looking through some old pics and found these pics of the toolbox I had in my old 87 R10 back in the day.  I think these are from 2002 or so.  About 4 years before I got my 78 I have now.  My dad came up with this.  I thought some of you guys might find this useful.

The way its constructed, is 3/4 mdf and 1/4 plywood.  Cut the mdf to fit the box front and rear wall, put 1/4" slots in them every 4 inches or so (fit the slots to the plywood you use for the dividers, it should fit loose enough you can pull them out easily).

The 1/4" plywood dividers have a notch at the top front to clear the toolbox lid when open.  You can move them around as you see fit, don't need to attach the mdf to the box as the dividers hold it all together.  you can have as many or as few dividers as you want.  you can also make as many or few slots in the mdf as you want.  Totally customizable.

Did you pull this sketch from the ones pined above?

I compiled the diagram from two separate diagrams illustrated in the '87 factory wiring manual.  It took a minute because there are circuit omissions in the diagrams that obstruct easy correlation.  You're welcome!

Yes. The in tank fuel pump comes on with key on, regardless of tank selector switch on the dash. The right tank operates as it should. Switch to right tank and the pump comes on. Switch to the left tank it goes off but the left stays on continually. There is key on power from those two tan wires. One goes to the dash selector switch and the other to the left pump. That's where I'm confused. Should there be two team wires coming out of that one bulkhead terminal?

I have kept the brake switch without vacuum hooked up. I'm letting the Terminator handle (-) control for the relay and the brake switch (+) for tcc lockup. Also plan to use the 4th gear grounding circuit as input for possible future tuning configs.  Thanks again

Thank you, I swear I looked through all of the diagrams listed for '87 but couldn't find this diagram. The ones listed/pinned say 1987 but are printed for 1988 and have more pins. I almost just put it back together where ever I had a free spot. But I stopped so I can do body mounts. I did find #420 on the other chassis diagrams but the bulkhead connectors didn't look right.
