craigm 25 Report post Posted October 20, 2013 I am installing a TCI rear torque arm suspension in my fastback. The panard bar brackets are mounted immediately behind the axle snubber flange. The problem is the rear frame rails have been replaced and I can't find the exact location of the bracket. Can anybody provide a measurement from the centerline of the rear leaf spring mount hole to the back of the snubber flange? Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted October 20, 2013 measurement from the centerline of the UPPER rear leaf spring mount hole to the back of the snubber flange I get 29 & 3/8". Brian Quote Share this post Link to post Share on other sites
craigm 25 Report post Posted October 20, 2013 Thanks, are both sides identical? Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted October 20, 2013 No. the Right/passenger side is the 29 & 3/8's and the LEFT/drivers side is 29 & 1/8. Perhaps someone else could get another set of measurements ? Brian Quote Share this post Link to post Share on other sites

craigm 25 Report post Posted October 20, 2013 Also, beautiful car. My first car was a "R" code Mach 1. I am building a restomod tribute to that car. Quote Share this post Link to post Share on other sites

If I were you, I'd mount the bar to the axle then just make sure the bar is parallel to the axle. Bob Quote Share this post Link to post Share on other sites
craigm 25 Report post Posted October 20, 2013 Detroit quality of the times! Could be measurement methods, are u guys measuring straight line or along the frame rail? Also, what is the width of the snubber flange? Quote Share this post Link to post Share on other sites

Also, what is the width of the snubber flange? I think 40 plus years of hard/high torque launches may have altered some of the alignments. Straight line measurements and 2" wide.

shelbyshelby 52 Report post Posted October 21, 2013 I just measured my 69 mach1 and it is quiet a bit different. The passenger side measured 28 9/16 from the center of the rear leaf bolt to the edge of the bracket where it's attached to the frame. The drivers side measures 28 inches. As far as I know it's never been in an accident, replaced or rusted. My rear is installed with global west shackles so the bolt heads are preventing me to measure exact line. Hope a few more measure.

craigm 25 Report post Posted October 22, 2013 Start with the passenger’s side cross member channel bracket with the panard bar bracket welded on. Slide channel over the rail and push forward until the bracket touches the axle snubber flange. See arrow. Quote Share this post Link to post Share on other sites
