Can someone ID my axle code?
 

I have a 71 half ton with a 12 bolt. I looked everywhere but I don't see an answer for my code. It's: THA W153.

Thanks for any help.

Anybody able to ID my rear gear ratio?
 

Can anyone identify my gear ratio?

It's a 1971 12 bolt.

The code on the rear passenger side tube reads: THA W153

T..'71?, HA..3.73 open, W..Warren MI plant, 153..153rd day of the year How does that match up to what you think you have?

HA = 3.73?

That would be awesome!

I just bought this 71 for a parts truck for $500, and I'm doing a 6 to 5 lug conversion on my 70. I just crossed my fingers when I bought the 71, but 3.73 is exactly what I wanted.:metal:

I will open the case when I pull it to confirm.
