Thank you in advance for your time and comments,

Look on your drivers post for the Viehicle cert label. It will give you a code there as to what you have. This is from the tech folder in Super Duty section

AXLE CODES:

37- 3.73

3L- 3.73 LS

41- 4.10

4N- 4.10 LS

43- 4.30

4L- 4.30 LS

48- 4.88

8L- 4.88 LS

53- 5.38

5L- 5.38 LS

 

First, WELCOME TO FTE!

Second, it looks like you have 3.73 gears, because the tag usually has the first number under the bolt head, so the tag saying "73..." really says "3 73...". And it's not a limited-slip Traction-Lok.

If it's a 2003 3.73 V10 with single-rear-wheels (not DRW) it's a Sterling 10.5"

 

Thanks guys for the replies, I really appreciate the comments and steering my in the right direction
