I'm looking at two deluxe Marti Reports and the dealer name and address are provided at that level. The base Marti report does not. Upgrading to the deluxe report (and paying the upcharge amount between base and deluxe) will provide that information. Otherwise, someone with a deluxe or higher lever Marti report for a car sold by that same dealership is your best bet.
Recognize that the San Jose DSO covers a large area, over the years dealerships have come and gone. The current fleet listing for Ford dealerships within 300 miles of San Jose shows 96 dealers. Here's the link.

Note that your selling dealer as well as a number of other former Ford dealers that I recall are no longer around. For general information the two local cars I have Marti reports on are:
Tuban Ford, Mt View # 72E032
Hughson Ford Sales, San Francisco # 72A005
I can recall other dealerships that are no longer doing business under their former names and include:
San Jose Ford Sales, San Jose
Jones-Minto Ford, Burlingame
S&C Ford, San Francisco
Ed Chavones Ford, San Leandro
Golden Bear Ford, Berkeley
Paul Swanson Ford, Los Gatos
Ralph Williams Ford, Daly City
Burton Ford, Sacramento
In addition, the Philco Garage on Fabian in Palo Alto (Philco Ford, later Ford Aerospace) was also the delivery destination of a large number of local cars for Philco engineers above a certain pay grade every year. If memory serves, those cars were DSO 84 or 89.
