For a late 12 V MT, it looks like the number is 31 073, but 31 072 
will probably also work, and there may be others.

I think later starters got shorter, so they would need shorter 
solenoids to match up with the pigtail into the starter. That would 
mean that you need a solenoid to match your starter, which might not 
be the same one you would get if you bought one for the year of your 
car.

If you give me the Bosch # off your starter I can give you the 
correct Bosch # for the matching solenoid.

Problems while hot may not go away with replacing the solenoid, but 
they might. I've had to let my car cool off once, in many years, and 
then it was fine again. This was on an AT car. A relay next to the 
battery should make a significant improvement in the loop resistance, 
as well as take a big load off the ign sw..
