1979 GMC Sierra Classic c3500 Dually

I’m sure this name has been used for a yellow squarebody before, but I would like to introduce my newest project that we have started calling “top banana”. I have been wanting to do something different for several years now. I have been a die hard 4x4 guy my entire life but we are stepping into the lowered 2wd world with this one. The truck is a 1979 Sierra classic c3500 dually that was bought new at Speight Buick GMC on Santa Monica BLVD in Hollywood California. The truck spent its early life in California before going to Las Vegas for close to 20 years. I acquired the truck from a friend of mine that owns a body shop. He bought it as a parts truck circa 2014 and decided it was too nice to part out. He threw a motor and transmission in it and enjoyed it for a few years. Fast forward to 2020 he decided that he wanted to do a 4l80e swap. The transmission was built, a converter was ordered, a vintage air front runner setup was installed and the truck was lowered with a 6/8 drop. As so many large projects do it got put on the back burner so he could serve his customers and grow his business. I have bugged him about this truck since around 2018. Well in April of this year he reached out and I bought the truck on the spot. There’s a laundry list of things to do but I am in the process of resurrecting this ole lead sled. The plan for the truck is get the Big block fired back up, install the US Shift quick 4 stand alone harness for the transmission, have anew driveshaft made, figure out shifter linkage, full vintage air setup, new tires, and I am going to swap the grill to a 73-74 style. I’m a big fan of roundeye squarebodys but it just so happens that the 79-80 front grille is my least favorite by a mile. I’ll have lots of update pictures to come but here’s the truck as it sits right now.

Here’s a few pictures after I got the truck home. And the second picture is after just a little cleaning with soap and water.

Here’s a picture of the vintage air front runner setup hanging off the front of the BBC. Second picture is a comparison of 79 grille vs 73-74. I have gathered all the parts and brackets to complete the swap after I hang the front clip back on the truck.
