I've got a couple RPO code questions:

1. My sticker list both U75 (power antenae) and V73 (fixed antenae). What gives?
2. What's the meaning of E5Z? (Speedo Adapter (delete) )
3. What's E9Z? (Speedo Key (Delete))
4. I replaced the 7R4 with a T-5 (so much more fun!!!) but my speedo reads wrong now....I just guessed and got a gear from Chev that fits in the speed housing on the tranny. I have an RPO of N96 (16x8 wheels) but I have 15's on it now......can you believe that some dumb a** before me removed the IROC 16's and replaced them with some shi**y 15" Chrome AR wheels? Hard to imagine......anyway, back to the speedo.....how do I get it working correctly? By the way, I have 2.73 rear end.

Thanks

V73 is actually:

V73 VEHICLE STATEMENT UNITED STATES/CANADA
---------------------
E5Z & E9Z go together, that just means that the rear end on your car wasn't the standard for that year model with that motor and the buyer ordered a different one.

You would have to have your speedo custom calibraded most likely
