I don't have any pics, but I'll have to go along with what crazylonghorn had to say on the subject.
This much I do know. My '72 LWB truck (all factory front disc/rear drum) has a much tighter turning radius than my '67 SWB truck (presently 6-lug, 4 wheel drum brakes).
I couldn't vouch for what lower A-arms that the '67 has on it.
I WILL be changing out the front suspension in favor of that off of a '72 plus adding ECE drop spindles and front anti-sway bar - real soon.
From what I've been able to gather the length of the upper and lower A-arms are the same from '67 to '72. The ball joints did change in either '71 or '72 but will still mount right into older A-arms without modding.
The difference is, therefore, the steering stops.
Don't know if I added anything, but I can hope.
