Another 66 GMC! The Wonton.
 

Been bugging a buddy of mine about his grandfather's old farm truck for years and finally managed to save it! Plans for this one are not nearly as extravagant as my short wide. Really just want to get her running and use her as a solid work/shop truck. My goal is to get it running/driving for under $1000 then enjoy!

Sweet! I love a nice long stepper

Got it into temporary storage and verified that the engine actually still spins over by hand, which is huge! Picked up a donor chassis to upgrade the brakes to disks, and also possibly swap over the rear end to have greater ease of finding replacement parts if need be. Not to mention a much more driving friendly gear ratio. I also picked up a carb for it off of a 63 C10 that also had a 250. Carb needs rebuilt, so that may be a winter project. Any suggestions on the best rebuild kits for these mono jet carbs?

Cool truck man. :)

Re: Another 66 GMC! The Wonton.
 

Thanks guys! Can't wait to have this out cruising in the hopefully near future.

Looks to be a good truck to start with. I love the long steps after seeing them more in person leading up to me buying a 8ft stepside, it seem's like growing up all I would see were long bed fleetside and short bed steps.

Can finally start updating this thread! After sitting for a year or so at the in laws farm, we finally got the free time to go collect this beast and bring her home. From there it was immediate cleaning of all the field debris still in the truck. Followed by a quick assessment of just what all it really needed to be driving again.

Found the receipt from the last time this old girl was registered and on the road. Also started putting many of my spare parts to good use. Swapped in a cluster that I had floating around, and also used a spare harness that was burnt up in another section to repair the rodent damage the truck had suffered while sitting in a field for the past 30 some odd years.

Had a carb that I snagged shortly after initially buying the truck that I popped on the ensure it was right. Had to build a small portion of throttle linkage, as the original was missing. I did find the original air cleaner laying down in the engine bay, so mocked it up to see how it looked. Also snagged a new under hood harness from Classic Parts, as the original was more than somewhat crispy and beyond salvation. The original master cylinder was frozen solid, so I pulled it and swapped it for a Corvette manual dual master. Hopefully this works well with the disk brake swap I plan on doing.

Glad to see you back to work on this!
Cool truck.

Re: Another 66 GMC! The Wonton.
 

Thanks! Really hope to have it driving by fall so I can have some fun with it.

Got some more progress made on the truck. Once the wiring was all roughed in I hooked up a battery and did some functions testing. Everything appears to be working, and there was no smoke, so that's a good sign. A previous owner had an oil pressure gauge that they just cut out and left the line behind the dash. Found a cool vintage gauge set on marketplace for a reasonable price, so I went ahead and swapped that in. After an oil change and being cranked over, truck does build oil pressure. I did however find that I was not getting any spark. Also discovered that #3 is low on compression, I assume due to sticky rings.

Man alive I am terrible at keeping these threads up to date. :dohh: Got this thing running and driving on the original drive train. Rear brakes lasted about a month and then called it quits. Because Eaton parts are impossible to find, and expensive, I opted to disk swap the 14 bolt I got with the other frame and swap it under the truck. Rocked her around for another year or so, and then got an offer I absolutely couldn't refuse on a trade for a late 55 NAPCO pickup...so sadly she's now off to greener pastures, and I now have a new money pit. A few shots of the progress as it went down. It was a really fun truck to get going again.

Wish I knew how to post videos on here, got a few clips of bombing this old rig around to the lake and around town.

Re: Another 66 GMC! The Wonton.
 

Well thanks for updating the thread, definitely a cool truck and hopefully appreciated by the new owner. If you start or have started a thread on here for the napco I will definitely check it out.
If you want to post videos on this sight the best way to do so is to upload your video to a online video sharing platform like YouTube, etc. and post the link for the video on this sight.

I think the new owner should enjoy it. He was quite excited when the old girl just fired right up and drove onto his trailer. I believe his plans are to pull the bed and put it on his NAPCO truck, then build a stake bed and use this old girl to haul wood on his ranch up in New Mexico. I'll have to start a thread on the "new" 55 truck here eventually. Haven't had a chance to do much more than just clean it up a little so far...
