The 914 looks correct in diameter but is coarse thread, while the spindles are fine thread.

When this happened to me I had to buy a pair from Rich @ HighPerformanceHouse of PartsHeaven.

Thanks...
After some reading, it turns out that there are 18mm and 16mm spindles, with the 18s' showing up somewhere around 73. I've discovered that most everyone only sells the 18...no 16mm clamping nuts.
914.341.671.00 M 16 x 1911.341.673.00 M 18 x 1
I read a couple threads that people found and ordered some 16mm clamping nuts only to find out they wouldn't fit because the pitch was different.
So it looks like a stinkin nut is going to hold-up my conversion.
Time to start looking...maybe parts heaven will have one?

Mark,
I found the same thing you did. There is a course thread on the 914 and a fine thread on the 911 spindles. I should have a couple of the nuts as I found at least one more spindle with the 18 mm fine thread. I checked the PET program and Pelican and they show a 914 part number on the 911 cars. I know that is not correct. I will see if I can find one today. If you have to buy one I will cover the cost.
