putting 1993 gt parts on a 1983 lx
 

Can you take the front nose, headlights, turn signals, decklid, rear bumper, rear tail lights,and side trim from a 1993 and bolt it right on the 1983?

for the most part yeah. The Fox3 chassis was basically unchanged from 79-93. You'll want the donor car handy and be sure to take all the fasteners with you and label them during teardown.
