Well I did one. I was able to pull my not so well done new one back out. The new one came with a rubber bushing on it. SO I used a dremmel tool to cut little slots in the inside part of the ferrule and after pushing it back in was able to use the tool to bend each tab down. The ring now does not move or spin in the door hole. Oh and the helper springs did lift the door handle back towards stock but 70 years of wear can't be totally erased and it still sags a little. Overall I am happy with the way the door handle and ferrule look. During this little operation I soaked the door mechanism to clean it and oiled it up and also the window mechanism so all in all the passenger door is working great and done for now.
