I am looking to buy a 1967 289 C4 Convertible but have a question about the Axle code. The picture of the VIN/Warranty plate is very clear. The Axle code is stamped "0". I have a copy of the Mustang Recognition Guide and Mustang Red Book. Neither lists a "0" for an axle code in 1967.
I'm stumped about this one...
Oh, and I did also check out this link:
http://www.vintage-mustang.com/topic...ml#axle_ratios
Which has the same information as my reference books -- no "0" listed.
Any help on what this is or how to check (is this info located somewhere else)?
Thanks!!!

Most of these decoders just copy each other, and the persistence of this one proves it. It's a zero, not an oh, and it's an ordinary 2.79:1 open diff, the most common 67 axle.

Thanks!!! That is very helpful.
Now for a "stupid" question:
I would want to change this to a locking/limited slip style (like how I had ordered my '89 GT). Is this a major deal (i.e. something that can be done in a garage with standard tools) or should I really have a local garage do it?
See, told ya it was "stupid"...

Never mind...I've check a bunch of other forums and it appears that I would indeed be quite stupid to do this myself.

Not stupid, but requires special tools and very exacting procedures. The best compromise is to get a Traction-lok center, pull your differential, and deliver them to a pro. When he gives it back to you, pop it in. For a little extra, you could switch to a more performance-oriented ratio, 3.55 is an excellent compromise. 2.79 will give pretty good mileage, though, which is why it was so popular then.

Thanks again.
Yeah, the 3:55 gears really woke up the 5.0 ('89 GT Conv w/5-speed).
I'll need to see the shift points/speeds if I buy the "67 to see how "deep" I want to go.
And mileage would be the least of my concerns with this car
Solid, reliable performance will be the goal - not a strip car but not a daily driver for sure.
