John -
I am assuming that the pciture you posted is from your original, unmolested Z-28.
If that is the case, I couldn't help but notice that in the picture, the axle housing lis natural (grey). Seems like in previous posts, when this had been discussed, the consensus was that the differential and rear end assembly was painted a semi gloss black. Am I remembering correctly? I much prefer the natural phosphate grey look to the semi gloss black painted rear ends.
Can you offer any clarification?
Thanks
Richard
