That sounds like an interesting geometry problem. Bumps and dips in the pavement go up and down in more or less a straight line motion.However the torque arm must swing in an arc to go up and down. That might be the cause of the binding that you heard about. I wonder how MM got around this. Maybe that's the reason why they get $$$ for the engineering that goes into their products.
Like I've said earlier in this thread, I planned to use that book to make the
suspension mods to the current project. 15 years ago, I did all of the stuff that book lists for front
suspension (changing front C/A mount angles for better anti-dive, raising the rack mounts to allow the front end to be lowered to minimize bump steer, grinding the strut mounting holes to allow the struts to tilt out more and afford more negative camber) it amounted to a bunch of very precise cutting and rewelding to the stock K member. I also made the T/A , mount, and the
panhard bar as per the plans as well I bolted them all into the then Current Fairmont project (which in the end ended up being a stinkin' drag car), and I traded all of the stuff I did to the guy that ended up w/ the T/A problems.
When this car came along, and i decided that I'd get a copy and do it all again, I contacted Griggs, and bought their front mount kit for their T/A, so the travel problem wouldn't exist on the new car. Their "kit" is nothing more that a piece of high durometer rubber sandwiched between the mount and the T/A, w/ a single grade 8 bolt that slides on a slotted mount to bolts to a eye welded to the front of the T/A.
Since I couldn't find the damn book, the whole rear/front
suspension mod thing got shelved, and I ended up going back to stock mounting the front and rear C/A's but used UPR rears in back, and stock, poly bushed lowers in front.
In retrospect, as much sh it as I have going on the stupid car, having to deal w/ some
suspension kink as a result of an irreversibly extensively reworked K member, or goofy assed, ground dragging T/A is just more meat than what I want on my plate right now.
