Rear Axle: Question about the rear diff

[evilhawk]

Seeing how the motor, trans and drive shaft had all been replaced at some time, I am going out on a limb here and guessing that maybe the rear end is not original to the car either. There are 3 tags on the rear end, one says "45", the other says "373" and the third was hard to make out but it looked like it said something like 400111 or 401111. I was wondering if any of you are familiar with these tags and could possibly help me ID it?

sounds like ratio 373 for one thing.

I think "45" means twin traction.

Nice, 373 gears and twin traction? That would be nice. I assume its a Dana 44 or maybe 45 is Dana 45?

Sam the dana 44 will have "44" in raised letters on lower right web. 45 tag denotes angle of cross pin in tt case, 373 is diff ratio. believe all domestic hawks "Started" life 44 equipped. Doofus
