1980-1981 ama superbike d.v.d

i've seen threads on another site about a d.v.d for those years...
i found the site once in japanese that was selling such,
i sent them a querry asking how much plus ship u.s dollers and never heard anything back...
anyone know about this dvd,,,,or any av. footage...i've seen one infield clip on youtube of an home video of lawson ..spencer..etc...anymore around ,,thanks peace craig

allright i got no bites on this one...i read it was not long minutes wise and the quality was not great but that there is a documentery tape(d.v.d)that follows the 1980-1981 ama superbike series...
I am going to buy it i just have to do some contact with the japanese before...i give em a penny on the computer...and they are not responding...also they only give yen numbers and want your credit card number...it said some crazy number...scairt the sh#t outta me..i'm gonna try and find the site it was a japaneese book clearing house...
i wanted to know if anyone knows about this movie they were talking about it on a german lawson site a year or so ago..
