Depends on the option when it was ordered new. The "Camper special" option came with 4.11:1 or the 4.56:1 for mountain regions. One of the standard gear ratios were 3.73:1 The off the line acceleration must be pretty impressive with the 4.56:1 but the top end and even crusing speed must be as bad as the fuel consumption!

the pinion and ring gear here.

What is the best diff gear ratio for the following bakkie, i think at present it is 4.44 or 4.11, can this be confirmed?

Go with what is in it. tags on the diff will tell you what you have. If no tags, then pull the plate and get the numbers off the ring gear. You may only need to replace bearings.

1976 chevy truck 4wd k20. I want to purchase a truck bed(8 foot) to replace the one in my bf truck. I have an offer of a 1997 bed. Can this bed work in a 76 or are the body designs too different?

It can be made to work, but it will require modifications.
If he wants to keep his truck original, keep looking for a '70's bed. A lot easier to install, too. Look in the southern and western states where there is no road salt used, that way you can find one with little or no rust.

Need front differential gear ratio? 99 Blazer, v6

3.42, 3.08 and 3.73 ratios were used.

You need to get under the vehicle and check the tag which has the diff ratio printed on it. The ratios front and back will be the same but look at both tags.
