I'm using early 911 cranks. Got them on eBay. Minor mod needed, but it's quick and they fit perfectly afterwards. 911 crank is in the back in the first 2 pics. Later ones were all black instead of chrome and black.
If you don't mind what was the minor mod you did ???

Sorry, I should have given the link---
http://www.914world.com/bbs2/index.php?act...f=2&t=99545The 911 spline has the correct number of teeth, and the major diameter is fine, but the ID is smaller on the 911 crank (teeth are deeper), Also the splined depth is deeper on the 911 crank, so it has to be relieved of splines entirely for about the first 3/16". So I drilled it out carefully on my drill press as follows:
Use a 27/64" drill bit, and drill down to the shoulder at the bottom of the spline. Then use a 7/16" bit and drill about 3/16" down into the spline. Last step- take a tiny triangular file and clean up the burrs covering the splines, and sharpen them while you're at it. Takes a few test fits and more filing, but it'll eventually fit nicely. It's hard to mess up if you measure carefully and set your drill press stops. The casting is farily soft and drills easily. I think I just hand held it on a piece of wood.
