hello. i am able to purchase a 1984 celica gt. i think it has a 2.2

i can pick it up for 70 bucks however, the engine dosent run and the transmisson does not have reverse. its an automatic and there is little rust exept on one fender. i was wonder if anybody could tell me how much parts are or how hard they are to find? and does anybody know where i can find body kits. or other engines would be a farily easy drop in? we have most tools and a shop. any other info or links would be apreciated as well
thanks
