Actually, 'More-Alice' is not correct.
"the dmv wont give me the name of the junk yard. can i subpeona the records from the junk yard -or- the dmv before going to small claims."
*** No. The reason is that you do not have the power to subpoena without a lawsuit having been filed.
"can i go to small claims and then subpoena."
*** In essence, yes. File your lawsuit first (this gives you the power of subpoena), then subpoena the records from the appropriate party.
"i dont know how this works."
*** California makes it fairly easy for a competent person to pursue a claim without an attorney (that is called 'pro se' or 'pro per').
In this case, since you are considering taking small claims action, I suggest you go to a local bookstore and get "How to Win in Small Claims in California". It is a very good book that will answer a lot of your questions.
As for the subpoena process, the form can be filled out online at:
