Re: Chrysler 18 spline hub
Here are two examples of 10 inch pinned props and a home-made hub pressing tool.
As far as I know, hubs for those props are obsolete and NLA. You can TRY HMS hubs.
The props themselves are becoming more difficult to find. Your best bet would be to search another used one on ebay or to "pin" the prop you have.
See my private message to you. I may be able to help.
