Identifying limited slip diff. & gear ratio?

[Trent4444]

If one was looking to purchase an "experienced" Ford E-250 or 350 Sportsmobile [ I am ] is there a way to determine if it has a limited slip differential [without driving it] and the gear ratio? Markings, placards, stamped numbers, etc?

Thanks,

Trent,

Look for the sticker on the driver door jamb. There you will find the axle, ratio, limited slip or not, engine, transmission, color and a couple of other items not usually revealed by the VIN.

Armed with this you'll need a decoder ring found for that year's shop manual. The decoding pages are in the first section of the shop manual. The decoding info may be available elsewhere but I have never been able to locate it outside of the shop manual.

Hope this helps™,
