I just did the switch last Saturday. The replacement is AMC pt# 3197598
- Filko 3527 (GM tilt wheel) or NAPA Echlin KS6622. To do the switch I
pulled the seat to make it easier (also to cant the seat) and got under
the dash. First, unhook the negative post on the battery because you
don't want the thing switching to the start position. There is a saddle
like thing that holds the column up and kind of hides the switch. It has
four bolts that hold it to the column and two that hold the whole
assembly up. Take this off -- it comes off easily and it makes the whole
job a lot easier. Then take off the two 5/16 little bolts that hold the
switch up there. Move the switch so that you get the little rod out that
operates it and move it so that you can take the plugs out and note that
you have to take both out together (as a unit). Plug in the new switch
and get the rod in there. Bolt the thing in, hook the battery and make
sure that all works and is in position then replace the saddle. Time --
about an hour the first time -- probably 30 minutes after you know how
to do it (the thing that took time for me was whether to remove that
saddle). Mine is a 74 but I think that the 75s are the same. If you have
any questions, ask away. Kim
