If you need parts list your requirements and use photos or specification or part numbers if you have them. If you are grounded please indicate the urgency level. Do not double post in other forums.
A Hartzell with the same length hub and spinner would be the least work for you. Do you want to change the weight or behavior in any way?
The new Hartzell composite, or the Whirlwind 300 might be a little faster. Both those are substantially lighter and would move the CG noticeably aft. The MT MTV-13 would work if want to go a little slower.
Send me a message, I have a propeller, no records on it but I have run it for 1,000 hours since I bought my 320. I am switching to a Whirlwind that I have on order.
