1929 phaeton wind wings

[jm29henry]

Hi sure could use some help!!! I am trying to get my car ready for 2019 nationals if you have any pictures of the correct hardware parts to mount the glass. On the wind wings .I am sure that the repo that the vendors sell are wrong especially because of the domed nut on the outside of the car and there is no washer between the body and nut . I think I saw a car at the old car festival in 2016 it was what seemed to me from memory was a flat cad bolt? And if anyone has or knows where I could purchase the proper hardware please let me know I thank you all for your help in advance joe
