1978 GMC Sierra Classic Heavy Half Squarebody
Long bed fleetside in original not restored condition. 454 V8, automatic, power steering and power disc brakes (front). Tilt wheel, cruise control
and air conditioning. Research shows that a Heavy Half (and the Big 10 in Chevrolet) had higher GVW ratings that allowed GM to not install
catalytic converters. It rides well and runs good. Except where noted below it is original and matches the equipment list in the glovebox (SPID).
Not being restored there are areas that still need attention but they very much depend on how the truck is to be used. Keeping it original might
require certain parts but modifying would require others.
We think the truck was sold new in Colorado and was moved to New Mexico at some point just not sure if it was the original owner. Two of my
friends owned the truck before me.
First friend ‘P’ knew the previous owner and about 13 years ago helped him to get the truck running after sitting for years. ‘P’ rebuilt the
Quadrajet carb and ended up trading for the truck a few years ago. ‘P’ sold the truck to friend ‘B’ who rents vehicles for local filming.
Second friend ‘B’ recovered the seat and dash and installed new carpeting matching the original color. ‘B’ did some basic maintenance, installed
new hood hinges and put a matched set of Hankook 235/75/15 whitewall tires on the original rims with the original hubcaps. Tires are date
coded about 2014.
I bought the truck to drive and help with a local house move after I sold my 4WD on Classiccardeals.com. For safety, I had the all the brakes
done by a professional mechanic. The headlights were replaced with the best Sylvania Halogens, the taillight lenses were replaced with
reproductions and the taillight bulbs were upgraded to LED. The spark plugs and wires, distributor cap, rotor and coil were all replaced as well.
The truck has dual tanks but the passenger side had not been used in years and will need attention.
