    Long story... but it boils down to always pull the diff covers to be sure what the gear ratio it is (yes, I know... everyone knows this already).

    Just when you see tags and stickers that indicate a certain ratio, and drive the truck and it feels like it has that ratio, you would assume that it is that ratio. And it would be... unless you are me.

    So it all boils down to... for me at least, never assume. Now I need to go find 4.56 gears for a 14 bolt and Dana 60 after I though I had them already. /forums/images/graemlins/frown.gif

    Prolly 4.10's if he drove it and it felt like 4,56's. I can't imagine it being farther off than that.

    Have you seen this dude's website? He's got Chevy truck HEAVEN in his backyard, a bunch of really nice rigs, and he's complaining? /forums/images/graemlins/rotfl.gif Granted it sucks to think you've got 4.56s and only have 4.10s or something, but damn dude, with as many really nice rigs as you've got with big blocks and 4 speeds, I wouldn't complain a bit. /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif /forums/images/graemlins/grin.gif

    Dont worry, Im not complaining. More like kicking myself because I should know better by now. They were 4.10s instead of 4.56s.

    Had I been smart I would have verified everything for sure before doing some axle swaps and ending up with a 4.56 front and 4.10 rear in my Truck Blazer. No wonder I snapped my front driveline at the last mud race. Stupid me.

    You know, now that you mention this, I'm gonna pull the cover on my '60. You've got me all worried now. /forums/images/graemlins/smile.gif

    Never hurts to check as I am finding out.

    Just usually Im too much of a tightwad to pull a cover if I dont have to. Pulling a cover means having to go buy more gear lube and possibly a new gasket or gasket sealer.

    Are '60 R&P sets stamped like GM ones are? Sorry I'm new to this Dana axle thing, I've had three different Corporate 10 bolt fronts. /forums/images/graemlins/smile.gif

    As far as I've seen they are. For example, today, when I checked my front axle (the one that actually was 4.56), it had 41-9 stamped on the ring gear... 41 divided by 9 is 4.555555

    4.10s is 41-10 on a Dana 60 verses Dana 44s Ive seen that are 4.09... 45-11

    Yeah, I,ve had similar stuff happen. I know it's not always convienent to check. I bought a blazer for parts. It ran, but the guy said the tranny was broken so I couldn't drive it. He said it had 3.73 in it. Well I bought it anyways. But it ended up having 3.42 rear and 3.08 front. AND a bad transfer case!! HMMMmmm, whoda figured
