In reply to jfryjfry :
The shifter drum that makes up the column under the wheel was the part in need of replacement. It is made of pot metal and had worn where the chrome shift lever pivots. Pulling it apart showed that the inside was even more worn. I got the replacement from either LMC truck or NPD which have pretty good coverage for this generation. It was a bit of a guess at which column option it was, but I got it right.
Don't get me started on old Ford turn signal mechanisms. This one luckily survived the R&R. I have an old Mustang that is on its 5th or 6th aftermarket turn signal switch. The reproductions are all garbage, having tried them all. Talking with the Ford parts places there are no better options currently. I can replace one in about 20 minutes though.
