69 C/30 cab to 72 C/20 frame

[t-bone1972]

I baught a NEW set of Kuhmo's (made in Vietnam) Right rear went out.
My BELOVED 72 C/20 saved 4 souls
(3 guys & a new puppy) after going offroading thru the trees.
Anyway, got a 69 C/30 and want to swap cabs.
Am I wrong in thinking, that this is simple as far as a cab swap goes?
All comments will GREATLY be appreciated.
I had the frame checked(good)
everything was new from front to back.
Will need new shocks though. (Duh)
