Thanks autoxcuda! I have been trying to locate some resemblance of a part number on the unit itself, but nothing so far. I have found both cast and stamped numbers, all of which have been 5 digit numbers. Not too many places on this thing that a number could be hidden! At least I can rest assured that I purchased a Detroit Locker, now on to find out if it's in operable shape!

I'm with you on the spool thing. Going in a straight line would be better done with a spool, I would think! I am a drag racing fan, but never been up close with a top fuel or funny car to observe the drivetrain. Kinda wish I could, though.

I know your Detroit Locker is an early one because it has the '68 and earlier style carrier bearings.

All the modern 8 3/4" lockers use the '69 and newer bearings.

Well, sir, I appreciate your input very much. Can you advise what the difference is between the earlier carrier bearings and the newer ones? Can the newer ones be used on the older lockers?

You must use the same part number that came off the unit. The carrier bearings are specific to the Locker, not to the third-member casting.

But this locker will work in my 489 case, correct?

Yes, the carrier bearings are specific to the Locker, not to the third-member casting.

OK, thanks. But, since the bearings are obviously still on the unit (I don't currently own a puller), can you possibly advise what part number and make of bearing that you would recommend?

I appreciate it!!!

BTT!!!

Pre '69 differential bearings/races: 25590/25520

I have them in stock.

Please E-mail me for more information.

Thank you, sir!!!

Doctordiff, I sent you an email. Not sure if you received it, since I have been having some issues with my email account.

Unfortunately, I did not receive it.

Hmmm, ok, let me try it again!

OK, I sent it again. I hope I have the correct email address. I used the one supplied in your contact info.

I still haven't received the E-mail.

You can also send me a PM me on this board.

Well sir, I just did that. Sorry, I have no idea why the emails aren't getting through.
