I had custom input shafts machined for my pilot project, and since I am no longer pursuing it they aren't doing me any good. The shafts are 16" overall with 10" of usable input shaft for the driven clutch.
I paid a hefty sum to have these machined to exactly fit the honda pilot transmission. I needed a new shaft with an industry standard size instead of the honda specific splines. With the 1" shaft I could use a wide variety of snowmobile clutches with my conversion.
Input shaft 16" overall, 10" of usable shaft for the driven clutch that is 1" in diameter with a 1/4" keyway.
This is exactly waht you need if you are planning on doing a sled engine conversion on your pilot. I have 2 of these and I want $250 each which will include shipping.
These parts are beautifully machined, and cost way more to have done than I'm asking.
