14 bolt, d 44 go to the 72 blazer under const. 203 get mated to the 205 in the 72 currently for a doubler then twin stick. d44 gets crossover steer once in the 72. seats go to 72. tires go to 72 for mock up (they are starting to rot). guage cluster with tach goes to 85 suburban (camping machine). install unused 10 bolts, 208, and misc. unused parts to 78 k5 and sell to try and recoupe some $$$.
