thanks for the info. I will look in those areas. also I've always been a Ford guy so I'm not to familiar with the GM history. but this truck was just to good of a deal to pass up, also i always wanted to restore a firetruck. the cab is a Spartan 80 tilt cab and but the center of the steering wheel has a GMC badge and there is GMC emblems on the engine and transmission. i was wondering why there would be 2 different makes combined in 1 truck.
