1965 Shelby GT350 request for info

I have recently uncovered some information about Mark Donohue driving a 65 Shelby (not 5R105) as a daily driver. Was told that a Dr Benjamin Poster purchased the car from Archway Ford Baltimore new but did not drive it much and Mark being new and from the area Ben let him drive the Shelby regularly. Any info or photos reguarding this would be appreciated.
