ok so i took the cover off today to find out what gear i had in my car because marking the drive shaft and seeing how many times it spins just didnt work.so i ttok it off and found out its a 3.73 but i also seen that a few bolts were broken and that when i spin 1 wheel by hand the other one does not move if anyone knows anything about lockers and gears let me know what the 2 broken bolts might be doing.you can see 1 of the pics the head is broken off the other one its broke deep inside and just hanging.the car was not making any noise at all i just took it off to see what gear ratio i had in the car and this is what i would

 

It looks like it may be a KAAZ, but they mostly make stuff for riceburners..stand bye

maybe?...a Drexler? (scroll down) http://www.drexler-motorsport.com.au/products.html

Whatever the case, I have several Ford units lying around, back in the day (late 60s early 70s) it was rumored that the Nelson bros that ran a very competitive Gasser Camaro used a welded rearend. From that time on welded diffs have been called "Largo lockers".

Anyway. I'm assuming that the broken bolt holds the pin that goes through the center of the carrier (probably under the snap rings) you may end up beating the living hell out of this thing to get it apart. In any case remove those snap rings and see what's there, you can rotate the assembly? right?

 

i think i found out what it is.its a detroit truelock .

yes i can rotate it i was driving it and never knew anything was wrong with it drives perfect

 

As I recall it might be fine (once you fix the broken bolts) the last Detroit Locker I ran (about 1974) you had to do a "chirpy" with it, in a straight line before your run. I know that they were absolutely bullet proof but had some bizzare characteristics that you had to deal with.
I guess they are now owned by Eaton

 

yea eaton took over a while back from what i was reading today
