Short shifter - Install gap on 1975 911S

[notmytarga]

I have the factory short shift kit from our host and am having a problem with a gap when installing it in my stock 1975 911S Targa.

Here are pictures to illustrate the problem:



There is a 4 mm gap between the supplied shift pivot housing and my 1975 shifter housing which does not have the set screw bolt on the front.



The stock arrangement is two overlapping brackets each of which has a length that is the same as the short shift supplied pivot housing - but they are overlapped - which adds 3-4 mm.

I am hoping there is a "correct" way to manage this. The three shims that were along this axis in the stock shifter add up to 1 mm - so I have an extra 3 mm to deal with. I will see if I can find a washer that is the correct size. My concern is that the roll pin is not substantial enough to compensate for the increased torque and movement the additional 3mm gap adds to the situation.

Have others dealt with this? What is the best thing to do?? Is there a different shift kit for my car with a longer shift pivot housing(it was listed as 74-?)?? Do I need to find a newer housing with the set bolt on the front? I'd rather not.

A bump to expand information.

I knew that the pivot cage shouldn't be allowed to slide along the roll pins because that would cause 'long' shifting as the cage worked along the pins when moving the shifter along the axis of the car's travel. Wearing of the pins would eventually make them fail. I got out my washer collection and found two that when placed on either end of the pivot cage filled the gap with no binding. I ended up not using the shims. The play was barely perceptible. It's all together now and feels smooth. It will be a day or two before I can test drive since I am painting my pedal cluster.

I would have felt better if there was less of a gap to deal with or if the kit came with shims. I would be willing to replace these washers with shims if that procedure is recommended by anyone. The washers were available and free - $225 to get a different shifter housing seemed a waste.

Anyone with similar experiance on a mid-year car??

For shift housings made prior to '77, You can insert an equal number of M8 washers or spacers on each end of the fork to remove play. Don't forget to lube any rubbing surfaces.
