[60-66]

Something I noticed when putting the thrift heater back in this truck. The lever control under the dash , the arm is longer on GMC. I have two NOS Chevy thrift heaters , was able to use some parts but not all. The cable/switch is different, wire harness also.

1962-1966 GMC Power Steering equipped front Inner fenders are also unique , they were punched for the PS hoses making the PS hoses also different than Chevy.

First with power steering in this era of truck. 1962 torsion bar PS from GMC only.

All the black metal under the hood , inner fenders etc on GMC specific plants the sheet metal is painted almost a gloss black when new . I have an NOS GMC PS inner fender and its gloss black as compared to anything Chevy.

Radiators , GMC , on some trucks used its own unique taller tank design. On others used the Chevy style. Mainly 1963-1966 models.

Air Cleaners , NO AC Delco units , all "United Air Cleaner" from NOVO Industrial out of Chicago.

Outside rear view mirrors , Re-Trac for West coast style , single arm mirrors and arms painted white instead of body color or Silver in 66.

Hose clamps are another item.

And of course the details of paint on the body door jambs and firewalls of GMC Specific plants

Theres more to come. I dont mind this discussion at all on this thread.
