There is nothing near me to test it. I did find a place in Knoxville, bout 1.4 hours, I'll plan to take it there. Over my nearly 50 years and as I'm sure you know; most places will not repair it unless you are successful in telling them what it's for...and not mention an airplane. In this case, I called, they asked me several times and I skirted answering. I will try to take it to them, but it will have to wait till next week as I'm going on a trip to help move a 9A. Here's the pics, everything I find close has something different, shaft length, pully location issues, bolt diameter, spacing, etc. Hope this helps giving me some direction.
I have one I removed and replaced with new on my RV7A, but it is different also. Thanks again
