my twin brother has a 91 leagcy that he bought wreck from the junk yard it was aready fixed beside the plastic inner fenders well for 600$ with only 65,000 orignal miles,you cant go wrong there its only 2wd later on in the year he went though a chain linked fence poped both turn signal out and busted one so he order a new 91 leagcy turn sigal, it was not right. we knew it had a new front end fender, hood, bumber, headlight, grill ect.... but it has the front end from a 92-94 legacy on a 91 legacy car

 

the whole font end of 91-older will fit 92-94 legacy are interchangable but it has to be the whole front end,fenders,headlight,turnsignal,grill,hood front bumper

Yeah you have to swap everything for the front ends to be swapped. Even then....there was probably some tweaking to make things work.
