This is a drawing I did of a 48-50 F1 rear upper shock pin. I'm not sure if they were identical in 47.
The pin goes right through the frame in those years.

Someone should be able to cross reference the part number to see if the pin is the same for a 48-50 F1 to whatever your application is.

Aftermarket replacements were unavailable last time I checked.
