Kodachrome Developing in home darkroom

Years ago I managed to develop Kodachrome by imitating the K-14 process with readily available chemicals. For the 1st BW development step I used D-76. I had totally forgotten about the removal of the REMJET backing, but most of it washed out when I dumped the D-76 out of the developing tank. Remaining goop was wiped off with my fingers during the re-exposure steps. For the color developing steps I used C-41 developer with color couplers added. I got the color couplers from the Rockland Colloid product "Selectachrome" which I think is now called "Multitoner" or similar. For the re-exposure to colored light I used a flashlight with colored plastic over it & slowly ran it across the film. I didn't have chemical fogging agents so the last re-exposure step was very long using a lamp held very close to the film. The bleach & fix was also from a C-41 kit -- not a Kodak C-41 kit, but from another company. The results were pretty good for just winging it. There were odd spots which I was later told were from using too much of the color couplers. I was also told that D-19 would be a better choice than D-76. I don't recall time/temperature o the developing steps -- I just made educated guesses.
