Re: '78 K20 to C10. Almost 20 years in the making.

I decided to try and use the mechanical trans linkage kit work as I wasn't sure the cable shifter would fit on my column.

I had a friend weld an extension onto the stainless rod that came in the kit.

I made a rough template of how I wanted the linkage to route from a hanger. I then used some map gas and the vice to bend the rod. After a couple adjustments I came up with this.



It works really well, surprisingly. I wasn't sure it would work right with the bends and heim joints but it does. So that's done.

.

I spent 2 hrs fixing the brake line leak in the rear of the truck. I had to use an inline flare kit and the old bar clamp style vice-gripped together to keep the line from slipping through the clamp. Eventually it was done and sealed. I replaced the hose as well as it was distorted from me overtightening the goofed up flare.
.
Right now I'm working on rewiring the dimmer switch and the wiper switch. I'm just extending the dimmer wires and cut the connector down and it plugs right in. I ordered a wiper delay module and then Ill be cutting the factory cab side connector off and wiring the existing wires to the connector on the delay module.

Re: '78 K20 to C10. Almost 20 years in the making.

Few things to update.

I was able to modify the stock battery brackets to hold this larger AGM battery. Its not super pretty but its hidden by the battery. It needs painted, etc yet it works. I need to come up with a hold down but yeah.

I used some battery cables I had laying around at work. The positive cable was perfect length and the negative was 1/0 speaker cable I had around. I found some crimps and some heat shrink from harbor freight.



I also mounted a universal coolant tank and got it connected. It was easier to mount etc than a stock one that I didn't have...


Sunday night I got to the point where I was ready to try and crank the engine over with the key! It fired right over without any issues. I didn't have any fuel in the tank so I wasn't ready for it to run yet.

Last night I topped all the fluids and put some fuel in the tank. I still dont hvae the right filler neck or hose but I used some heater hose and a funnel to dump in a few gallons. It struggled to start and was dumping fuel badly and running poorly. I realized after talking with a friend that my choke wasn't working right. I got that handled tonight and made another attempt.

Finally running after a few fixes.

Tonight was the first time Ive ever driven this truck under its own power. Pretty stoked about that.

Please excuse the poor video. My wife texted it to me instead of email.

I still need more coolant. I feel like this things holds a swimming pool full of coolant. The trans is pretty close to topped off. It was hard to read in the dark. I had the fan running to keep things cool.

Transmission seemed to go into 1st, neutral and reverse just fine. Thats a nice relief. Brakes worked so far. Pedal seemed a bit low but not spongy.

More to come. ..

Good progress! Nice to hear it make some noise. Battery looks fine. You should see the box the previous owner of my plow truck rigged up to hold a 4D battery...
