original parts does have a decent selection but theyre insanely expensive. what kinda of parts are you looking for? the body stuff is tough to come by since it was a 3 year only body. everything else you can source from just about any monte carlo 79-88. i believe 78 had a little bit of a difference with the brakes and what not.

 

nvm guys i wrecked my truck and now i'm lookin at sellin my monte were i have something to drive for a job thanks any ways
