They have 3.54s made just for that. Will cost you the gears and a new carrier though.

nope, your current carrier will work. the split is 4.10 and down, and 4.56 and up. just need the gears.
EDIT: I'm not sure if I'm reading your question right...lower gears would be 4.56's. But I don't see how that would get better mpg (except in town). If you want 4.56's, you need a new carrier. If you want higher gears, you are good to go on the carrier.

1969 GMC, she means lower number or a higher gear ratio. Crystal, IMO you should run at least 308's with your present set-up. The truck will most likely put the speedo needle in the p of the MPH at wide open, Gas mileage will improve.
