I got my microfiche back in the day when I worked at a dealer parts dept. From what I understand they are all computerized now and no one uses "fish" anymore.Microfiche readers are the hard part,try to find one of those! I also have many O.E. paper catalogs that I kept from my parts days.
The best advice that I can give on the parts reference materials is this:
Find someone at the local parts store(a real parts store not AutoZone)who is smart,understands what your doing and will take the time to help you.
Always deal with that person whether you have to wait for them,call them back,etc.
Buy everything from that person,even if they are not the cheapest in town.
Help them,a case of beer, tickets to the local races,whatever...
Good Luck
