HI There,
I'm trying to make some sense of the rearend tag on my 62. It is the small one, I think 7"? The numbers seem different from any of the decoding charts I have seen. Any words of wisdom out there?

The number;
C2 UA4 00(?) GEL 752
3.50

The unit appears to painted red under the old gunk. The entire unit seems small, almost toy like. Does anyone know what I have here? Are these reliable units? Any accessories, parts etc. that anyone knows of?
What of the 3.5 ratio? This is linked to a 80's 250/C4. Is this a fairly economical ratio MPG-wise?

Many Thanks! Mike

 

The 3.5 ratio is a good one for MPG and still have power.

Can you post a pic of your rear axle?

I don't recognize the tag numbers. Could the rear axle have come with the 80s engine?

 

HEre you go. Thanks for your time.
