JL8 12 bolt verification

[race-rodz]

can anyone verify this as a JL8 only deal? supposedly dealer installed JL8 rears didnt have the tapered tubes.

im askin cuz i have a 1st gen 12 bolt with 11.5" disk brakes... with the tapered tubes..... i figured it was converted at somepoint...but after reading this article..im curious.

Got any axle ID stamping numbers? Should be on pass. side tube facing forward.

To my knowledge, the tapered tubes are not isolated to any particular 12-bolt axle configuration.

For a definitive answer, I would post this question on camaros.net for Kurt S.

thanks... i had allready checked into it a lil more, turns out its a BL1031G2...meaning its a 307 open, casting code is j137...making it a 68 model year. as i had thought...somebody added the 373 posi and the JL8 style 4 pot brakes.

basically i have a nice piece that isnt worth a lot to anybody in the resto crowd.... now i just need a 1st gen to go with it :D
