...for all years, '68-'82. Already have the following: 69, 70, 72, 75, 76, 78, 80, 81 and at least a partial of '74. Only need a few more for completion.

In research for a possible sticky or tech tip on the subject, I'm attempting to compile a comprehensive listing of all factory Z, D, J and K "trim height" specifications covering each and every model variation produced during the generation. From year to year, other measurements may be given, but as only these partiucular dimensions are relavant, no fender height, tire clearance or otherwise ad hoc measurements are sought.

This info can be found in the AIM and/or factory Service Manual for each year. For most years, there will be multiple listings for different combinations of engines, suspensions or other options. I'll need them all. If you have that info and don't see it listed above as already in hand, please post up.

Thanks for the help. I hope, as an important part of a larger topic, the result of this compilation comes to serve as a valuable reference point for all C3 owners.

Thanks, MIKER, but I'm only looking for the specific dimensions shown below.
