Finally found the stamp

Finally found the stamp


Senior Jeeper
Kihei, Hawaii
77' CJ-5, 360 c.i. motor, T-176 trans, D-300 transfer case w\ twin sticks, Dana 30 front, A.M.C. 20 rear w/ 4.10's, solid axles & trac-lok, 2.5" lift Y.J. springs.
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.:rolleyes:

Sorry- just had to tell someone.:chug:

Just shows everybody gets lucky sometimes.
Wish my would have came with a 4:10. Would have saved me a ton of money.
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.
you are lucky!!!! pretty sure mine has the 2.73 the way my jeep is set up. i have no take off with 31" tires.
