Rear shock muonts

[pkort@cis.picker.com]

  Now that I managed to remove the rear shocks  on my 1969 1600, I find
myself in need of a new set of nuts used on the upper mounts ( no blue
comments required! ).  My guess is that they were cross threaded back in
1975 when the PO had some "NAPA Regal Riders" installed.  Does anybody know
the thread size and count?  I'm hoping NAPA sells something the correct
size.  We have had too many good weekends already this year to leave the
car up on stands much longer.
