Look for the X11 or X44 code on the trim tag for starters. Get all the information off the trim tag on the firewall and post it here. Also post the VIN or most of it to help determine the date range and if it agrees with the trim tag. Does it have a cowl hood that's original to the car? Does it have a 12 bolt posi rear(if so look for the codes on the passenger side facing forward, it should be BE followed by some numbers and a G like BE0405G1), it should have power disc brakes, there should be no holes in the fender for engine size emblems, it should have a big block heater core with the hoses in the middle, does it have a radiator with a curved neck, if the trans is a 4 speed get the codes off it to determine if it's an M22. Hope this helps for starters.
