What 7secondchevelle has up for your consideration is a new 8" or 9" Ford Track-loc style posi clutch hub. 31 spline hubs are also available in another of my listings for 9". Read on. No APO or P.O. Boxes. Must have physical address only. Shipping is to the lower 48 states only. All others will need to contact me first for a shipping quote. I ship only to USA addresses. If you are out of the country I will ship to your exporter here in the US or you can use eBays global shipping program. I will not ship directly out of the USA. I will not be held responsible for non or under insured items. Local pickup is always OK. Please email me with any questions or for any additional information. Thank You and God Bless.
