Looks like a 36 to me, at least has a 36 grille. I'm not an expert on 35-36's but I believe if it has a large X stamped into the cowl side under the hood then its a 36.
Hard to see the if it has a lot of rust in floors etc. but if it's pretty solid in those areas, around here it would probably bring around $8,000 to $10,000.
