Jim, the best I can recommend is to get the Factory Service Manual(s) for your car. For a '75, you would also need the '74 Service manual, since the '75 manual is really just new additions to the '74 manual. You can find both the hard copy manuals, and CD versions on ebay all the time, for fairly reasonable prices(around $40).
You might also want to consider getting the AIM(Assembly Instruction Manual). This is what the assembly line workers used to tell/show them how to assemble the cars, and what parts to use. The AIM is prolly the most valuable book you can have, imho.
There are many other Restoration, and modification books out there....I have many, but no specific titles come to mind right now....I'm having a senior moment....
