Look through the 'discussion' tab in that 'how to'. I thought that was where someone pointed out or linked to information on the '67 columns.
I can look through my notes and files later in the week.
Ya Its in there. the 67 column starts to come up in conversation around post .....67....then like post 75.....and then a couple more....good read.... great inginuity. Some guys added a swivel right before the steering box. There was talk of binding and stuff that Ill read later but I forgot my glasses and Im at work now.
