92 C/1500 steering box into a 67 C/10

[Inverter]

The 1500 box is on the inside of the rail,the c-10 box is on the outside.The mounting points are opposite.Your idler arm and drag link wont work either.I wouldnt open up that can.Could be done but its just not worth all the labor to still have an antiquated setup. You can get a better model specific box and skip all the headache and down time. Thats my $.02.
