Thank you Gents I think I have it figured out. So to recap. I have a 1967 C10 fleet side long bed with drum brakes all around. The goal is to switch it over to disc brakes and keep the current ride height.
I measured from the center of the spindle to the fender lip and had 19" in the front and 19-1/2" for the rear. I also went ahead and measured the distance between the bump stop pad and frame. For the front I measured 4-1/4" and the rear 8". I got the assembly manual and on page 251 it had a chart which gave the distance for the front bump stop to frame distance which was 4.21".
So based on everyone's input here, the other thread and the assembly manual I have come to the conclusion that the ride height in the front has not been changed. On the rear I would say it has been dropped slightly based on the fact that three coils are touching each other. Now I can come up with a plan. Thanks for your help.
