I just bought another truck last night (yea!!!), though it's not a Blazer (close enough). It's an '84 K-15 pickup. Mostly rust free (next to impossible in Wisconsin) for only $400! It origionally had a straight 6 and an SM465. Last owner had a 350 4 bbl swapped in and kept the SM465. Still has 10 bolt front and rear axles. I checked the glove box for ratio codes, and only came up with: G80 - Limited Slip GQ1 - "Standard ratio for merchandise pkg." Anyone have an idea what the standard ratio is? The truck is very plain, just a standard Sierra, not a Sierra Classic or High Sierra. No big deal if no one knows, as I'm asking for a 60 and 14 ff for Christmas Dave Hiller 90 K-5 "The Anti-SUV"
