Need Pic F body 12 bolt BE

[beater68427]

I pulled the 12 bolt out of the 68 Camaro, It is a late date code 68 I think it is oct I will have to look tonight, BE code Im guessing it is a 69 rear no vin on it, Has 4:88 gears currently, Im going to put 3:73's in and blast it, I wanted to see some pics with correct markings on axle tubes center brake drums etc, Also any ideas on the best place to get repo multi leafs, the springs in it have been modified with one extra leaf added to the rh side, so I thinking of changing them out, Or should I leave the vintage modifed stuff in??
