A lot of questions that appear over and over again here are answered in the shop manuals. While they may be available elsewhere and on line, at least one of the T Bird vendors is now selling them in CD-ROM pdf format for $22.00.  I am not specifically recommending this  vendor but they seem to be pretty reliable in the T bird world.
