Dee,
The distance between the bulkhead and the pin has been getting shorter for a couple of years. We noted some difference in the measurements in units that did not have the new design cap with mirror. Maybe not the 16 full inches that we measured, but some. By the way, we chose two 3400's, early model and almost hot off the production lines to study, made it sweet that they were sitting side by side at the Rally.
Nothing like a Rally to really look em over and find the changes!
