Hi, i need help identifying my rear differential on a 82 F-250. The tag on the differential reads as follows; 3.54 E2TA-BKA 605040 6 L S .The tag was difficult to read , i believe i have it correctly. Thanks.

 

Sounds like a Dana 60 3.54:1.

 

thanks for the reply, but i need to know for sure in order to buy a locker. how do i tell if it's a dana 61? all i know is that it's not a 9 inch ford because the bolts are on the outside.

 

It definately shouldn't be a 9", as they were only put in half ton trucks and some cars.

It's probably not going to be a Ford 10.25" because they weren't introduced until '83.

I hesitate to say for certain without seeing it, because a lot of the time you just don't know what's under these things after 20 years.

Try this link. You may find it useful.

 

You may could try calling or emailing DynaTrac (?? spelling) with the info. They guy I dealt with was very helpful and they replied within a couple of days when I emailed.

 

That's a Dana 61 Full Float, 3.54 ratio according to Dana's website. But it also shows to be for the F-350 instead of an F-250.
