Early A Throttle Pedal Assy.

Have any of you early A guys replaced their slant six throttle pedal assembly with a later model cable-type pedal assembly like pictured below?? Seems like a pretty straight forward swap. Am I missing something?

I have, but that was about 1975, so I don't remember the details. If it was difficult, I imagine I wouldda remembered,lol. I do however, remember the goofy slanty stuff I removed,lol.
