Gear ratios used in 67-68 2wd's? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Sorry, posted this in the wrong forum earlier.

I have a 68 2wd LWB, 3 speed on the column, and it originaly had a V-8 (not sure what size though). Short of pulling the diff cover, I was trying to figure out the ratio.

I tried the tire-to-pinion count, but that was weird.....1 full spin of the tire netted 1.8 turns of the pinion. I could not find a tag, or any stamping on the tubes (to much junk built up).

I will pull the diff cover someday, just wondering if anyone had an idea of what GM threw in there back then.
