VIN decoding conflict???

[Big Bobby O]

Hello everyone,

I'm have a little problem. I was given a truck and the VIN doesn't match the truck. As far as I can tell from some internet searching (see below), the vin comes back as a 78 1/2 ton, 2wd. But the truck has 8 lug wheels and is 4wd. As for the year, I can't tell because the tag on the driverside doorjam doesn't have a date stamped. Just the vin and the GVW numbers. And I don't know if the GVW numbers listed are consistant with the 8 lug wheels. There is no VIN tag on the driverside dashboard and I don't know what year they started that.

Any help would be appreciated.

Vin Decoding Results
VIN TCU1481XXXXXX
Model Year 1978
Division (unknown code)
Chassis 2 Wheel Drive
Body Style Pickup
Series 1/2-Ton
Engine V8 305
Assembly Plant Flint, MI
Sequential Number XXXXXX

The VIN door tag gives that vin number and lists a GVW of:
05400 - 3100 front, 3210 rear
plus some other "camper loading" info - (?) GVR0863 DIM A 077 IN DIM B 004

Does any of this make sense???
