Just to add to this thread, although Mark has already answered:
He (Mark) is a great guy, and Lateral Dynamics is fantastic
. Be patient, LD are definitely extremely busy, but his 3-link kit is well worth the wait!
I live in the UK, Mark managed to get a kit out to me by Christmas Eve last year! - basically a week from the day I ordered it!
Can't speak highly enough about him, well worth talking to him as well
to Mark and Matt
