Just what it says (lol). Pulled this rear out of a 60's little box truck that was a old ice cream truck, tag id is top line WFP-A1 1FD lower line 3L70 8 7 650A The only thing i find close is 70 bronco??? any help would be great

 

Is this an F series based truck or a forward control truck?

Should be a 9", but I don't find that code in the decoder ring I have, and the ratio should be 3.70, limited slip, based on the tag.

Any chance some of those letters got smushed and might be something else?

 

Not sure it mite be forward control truck it had a 4cyl in it. No i can read them fine...the only thing that mite be different is after the A on the first line it could be I not a 1.

 

I know it's a clumsy and hardly scientific way to tell, but a pretty good way to determine whether you have an 8" or 9" is with a socket and a 3/8" ratchet. If you can get on the two nuts beneath the pinion snout with a ratchet, it's most likely an 8". If you can only get on those nuts with a combination wrench, then it should be a 9".

Also, I've never heard of an 8" coming with a 3.70 ratio, but I haven't heard it all yet...

yeah it's a 9. well not quite from what i found it's 8-3/4 thats why the tag has 8 7 after 3L70. thanks for the help
