That's what my truck has as well!

 

^^ Trade?

I have a very nice set of 3.55's... that are open and very clean

 

Haha! I like it a lot, especially since it's 2WD. When I bought it in February, I was lookin at the tag, first truck I've owned with a LS. I got two F150s and 2 FS Broncos back in my hometown. 4x4 truck has code 19, other 2wd is code 12. My broncos got code 18 and code 19.....

 

The chart lists the capacity as 3300 for a '71 Code 17 and a ratio of 3.25, maybe it was for a 240 powered F100? Or F110? I know 82 or 83 was the last year for F100s as my dad had one when I was a couple years old.

 

Probably, I'm not keen on what was in the F100's, I know there was some odd combos though.
