I have a 1986 F150 302 4X4 automatic w/ overdrive. The driver side door codes are all removed, so I am unsure what rear end and trans I have.

I pulled the codes off the rear end and trans, any help is greatly appreciated.

Trans code:
RF-E39P-7006

Rear end code:
5910P
55 88 6C03

Also, would the rear end be limited slip? I am assuming that it is not because when the rear tires are off the ground and I turn one tire, the other one turns in the opposite direction.

Thanks

 

You have a AOD transmission and you are missing some numbers for the rear. But it looks like you have a 8.8 rear with 3.55 gears.
