so ive got a 93 legacy and im looking for a factory service manual but the only one i can find is a 92. where there any real differences between those years or will the 92 manual work for me?

92 has clear rear turn signals and uses different rear lateral links and endlinks.

 

Other than that no mechanical differences that I know of.

Yup, Jamal hit all the ones I could think of too.

Yep. As far as service manuals are concerned, there aren't any real differences. Keep an eye out for wires that are different colors than the schematic says, but everything should function in the same way.
