Rolex 1680 need help with identification

Hi looking to trade , my rolex film 14060m and gmt 16710 for 1 red sub. My trusted local vintage seller had 2. Can anyone help

  1. Rolex 1680 mk6 1973 ghost insert , end link 580, bracelet 93150 , only watch: still bargain

2 rolex 1680 , 1972 , i believe mark iv, bracelet 9315, end link 380 , insert grey shade on lighter side : 2 watch + 2000-3000dolar

First of all I am ok with part swap as long as it work with the watches and I already know before purchases. This is very old watch with a lot of similar model. So I hoped some one can help me identify just dial and insert, I am ok with swap bracelets
