I've got copies 1,2 and 3 of Proflex's Suspension Times which has 856, XP series, 857, Noleen etc in them. Not sure how best to post them up as they are several pages long each.
I had a 750 (replaced under warranty) with a 752, in turn replaced with an 952 frame....
Bob Girvin now races a classic car. he will probably be at Silverstone in July.. Or look out for GT racer on Dave or on DVD on Amazon.. You can walk round the paddock and get up close and personal with the cars and teams.. Brands hatch has a race that is part of the same series at the end of May.....
