Hey can anyone tell me what this L34 and the other codes on this chart for SS http://www.camaros.org/diffs68.shtml Any help would be great.

Also where is this L34 found on the trim tag or where?

 

uh...i dont really understand the question, but i glanced and it just looks to me like the L34 is the same in basically every way except its got a little more power than the L48 and L35 and less than the L78...as far as finding the tag, all i could find out was this....
Location: Small block Chevy - on the machine pad in front of the passenger side cylinder head. Often hidden by the alterator. Big Block Chevy - above timing chain cover
