Taligate Lock / Window winder issue

[eighteenninetytwo]

soooo got the 75 back - SO much fun driving it again. However I need to be able to wind the window down to open the tailgate. The old handle had no key so the shop had to take it off to paint and couldn't replace it. They recut the cylinder for a new key and set it in an new assembly. HOWEVER, the old cylinder just falls out of the assembly and I cannot get the window open. ANYONE know where I can buy a DECENT rear gate winder / handle??
