WWW Page/Tiger for sale

[Graeme S Sutherland <G.S.Sutherland-MSCCG96@cs.bham.ac.uk>]

        I found this Tiger for sale the other day:

        66 Sunbeam Tiger fair to good, 61,000 miles, slight rust in
rockers & doglegs, LAT 70 wheels, straight, Fast. $12,000

        For more details, go to:

        http://ourworld.compuserve.com/homepages/jhaynes/

        Could someone please explain to me what these LAT options are. 
Despite having a long and costly education at some of the finest
establishments of the English-speaking world, I have never been taught
these important facts...:)

        Thanks.
