neediff. ID on 2PJ G188 thanks

The format you indicate is a little confusing to me. Should be in the form aa mm dd f s. Where aa is the axle code, in your case PJ; mm is the month, dd is the day, f is the plant, and s is the shift - either a 1 or a 2 for first or second shift.
Assuming, from your username, we're talking about a '68 -
For either '67 or '68 model year; PJ decodes as 3.73:1 ratio, 12 bolt rear end, positraction (If this is a '69 axle, PJ decodes as a 2.56:1 ratio, 10 bolt, posi rear end)
G = Detroit Gear and Axle Plant; 1 = 1st shfit
I'll defer to others as to what the 2 at the beginning or the 88 at the end mean.
Also check the CRG axle decoding section at the following: http://www.camaros.org/drivetrain.shtml#RearAxleNumbers

Can you verify the "2PJ" again? I don't have a code like that listed. I have 2PU listed, but not 2PJ.
By the way, that format is for a mid to late 70's Nova.

its 2pj 541/2 backing plate to backing plate thanks for all the help

It must be a later axle than 1979, or from another car. The NOVA SITE (http://www.novaresource.org/axle.htm) only goes to 1979. Is there a casting date on the pumpkin?

more info on rear on pass.side has gm30 on diff housing driver side #1254333 on housing casting date f 25 9 on pumpkin

F259 would be June 25th, 1979, so it's not be from a Nova since they show 1979 codes.
After doing a basic Google search, I came up with a 1979 F/B-Body Pontiac 2.41 open (http://www.teufert.net/pontiac/rears.htm).
