Factory assembly does not show photo or reference for my spare tire carrier on my 1950 Chevy (1953 and up in the book). Do you have anything on record (photos) pertaining to this issue. Trying to figure out the built of the 3/8 pin that slides inside of the track that needs to be about 2 1/2 inches long. Did the pin have rollers or was it just a straight pin? and the securing of the carrier bracket. I had a homemade bumper on the rear end and don't have exact details on its mounting. Hope I'm in the right Forum. Thanks
