I have just recently purchased a1967 C-10 truck because I felt like having a hobby project truck. The thing that struck me as odd is the HEI distributor, O2 sensor, and the center bolt heads. I looked at the tab at the passenger side front and didn't find any markings on it, so I looked on the back of the motor and found two numbers. 57lg and 10054727. Am I seeing these numbers right? Where else can I look to make absolutely sure of what I have.
I didn't want to start a whole bunch of threads nit picking as to what fits my truck so if you have anything that will fit ( rotors, seats, dash et c.) drop a post because this truck is going to need all the help I can get.
