Should i get or stay away? (ALOT of pics)

going to need more pics, trunk , quarters and extensions and frame rails. its looking a little rough up top. the floors look pretty bad. ive seen much better for 1000-1500. in my opinion "matching numbers" 318 doesnt mean squat. the added bonus of a 318 in a 73 and up is the disc brakes and BBP. an 8 1/4 would be a plus. the trans im sure is a 904
