I just finished the front suspension on my '68. The spec on tightening the front strut to body mount nuts in the manual is 60-80 ft. lbs., but with the new bushings (they're stiffer than the stock ones) they don't collapse the same. Does anyone have a good guideline or information on how much to tighten or crush the strut rod bushings? Should I keep tightening them untill they collapse down to the length of the inner sleeve?
