Help with part ID's on Lincoln parts car

I bought a '71 Licoln Mark III for the 460 and C6. Here are two things I would like some help identifying

1. It has a Holley 4V carb, but I can't see any part numbers on it. How do I i.d. which carb it is?

2. The door post tag says "Axle 4". Is this a limited-slip rear end (assuming it is still the original) and what is the ratio? There is also a warning light on the dash that stays on that says "Sure Track" if that helps. I have a 3.70:1 trac-loc in my Torino, but I thought the Lincoln might supply me with a set of "highway gears."

Thanks for your help.

Not sure what the "4" means, but if it's highway gears you want I got a 9 incher in my 79 T-Bird with 2.50s.........[img]/phpBB/images/smiles/icon_biggrin.gif[/img] Wanna trade?

Here is what I found for axle codes on a 1971 Lincoln.

4 = 2.80:1
6 = 3.00:1 Optional
M = 2.80:1 Tracton-Lok Differential
O = 3.00:1 Optional; Traction-Lok Differential

It looks like you do have "highway" gears after all.

Here is a link to more info that you may find helpful.

Thanks for the info and the link!

Kywookie - Sorry, I'm not looking to trade. I just thought it might be nice to be able to switch to the Lincoln gears to say cruise up to Woodward. I don't know if I'll ever do it, but I will pull the third member so I can if I want.
