Rear End Question

Hey Guy's got another question. Sorry to ask so many, but this is the best place to get advise on stuff.

I the 1961 F100 and got to the rear axle and it has the following on the tag.

CITT 4001 J I know it is the i.d. number

Then beside the i.d. # is 102

Then below it is

3 70 1G ( I know it had 3:70 gears) but curious what the 1G for as well

Thanks in advance. There is a lot of knowledge on the Forum.

“Rear End Question“

No, your dress doesn’t make it look fat, you’re fine.

I can’t decode it, but someone will help you out directly . . . Sorry, can’t help myself.

After I posted it I thought I should have changed the title. My wife always asks me " how do I look in these pant or does this shirt make me look big "

Ford 9" rear axle / 3.70-1 / 3,300 lbs. rear axle capacity.

The rest of the jazz had to do with change level and the assembly plant, which could not be decoded.

o,k. Thanks.

I know on newer cars they put a "L" on the gear ratios and that means a locker, I did not know about the 60's. I know it had a huge tag on it bigger than my 64. One guy came by my house because he seen the truck in my driveway and said that look like a positive rear end and that had me scratching my head.

Thanks Again

Limited Slip (L/S) introduced in 1959 Passenger Cars and F100/250, but the 9" wasn't available with L/S in F100's until 1968.

Dana 44 with L/S 1959/67 F100 / Dana 60.2 with L/S 1963/66 F100 / Dana 60.3 with L/S 1966/67 F100.

My 1965 F100 had a Dana 44, the tag was under two of the bolts that retained the inspection cover to the housing. There was another tag w/an L on it under another bolt.

Why have two other options for L/S besides the 44? Who the hell knows, FoMoCo did some weird things back then.
