Finally found the stamp

[Buuushman]

Scraped the crud off my model 20 rear and found the factory stamp- M - Trac-lock and 4.10 gears, this thing is gonna scream when I finally get the 4-spd in it.

Sorry- just had to tell someone.

Just shows everybody gets lucky sometimes.
Wish my would have came with a 4:10. Would have saved me a ton of money.

find you some 4 banger axles should have lower gears in it right?

I would have rather had a open diff with 4:10's so you could put a lockrite Locker in it. The trac loc's are junk.
