A great big thanks for everyone who contributed info for, and to, the KDP fix. Last weekend, I did mine the long way. Remove the
front cover (I wanted to R&R the ft. seal anyway) and staked and
green LockTited the pin. As of 114K miles, the pin had not moved.
For once, (and I mean once!!) the diesel gods were with me... .
Thanks again, everyone who brought this to our attention. .
