[InkedinRI]

hello i have been looking at this site for a few days now. i bought a 1968 chevy c10 vin# CS148T1xxxxxx i know its a 1/2 ton 6cyl truck from the vin. what i don't understand is today i removed the wheels it had on it 6 lug Aluminum wheels off a newer chevy truck, to find hidden under the center cap 8 lug axles? someone put spacers on to use 6 lug wheels. it was my understanding only 3/4 ton trucks have 8 lugs? i thought someone mite have put a 8 lug rear end in it, but it has 8 to 6 lug spacers in the front also. can someone fill me in on what the hell i have?
