Frame differences?

[Farmer]

Let's see if I can get this question right,lol

 

Other than the gas tank mounts and king pin / ball joints suspension, is there any other differences between the 73-79 620 frames?

Larry, the only differences that i know of are the upper control arm mounts that changed for the 78 model year(disc brakes). And the crossmember that changed for the late style gas tank(79?, maybe 78 too).

I brought this back up to the top to ask another question.

 

Ive spent the last hour reading here on ratsun and have a few question about the 720 frame. And in doing so, I want to reaffirm my findings

 

This is between a '78-'79 620 short bed frame and a 1980 720 Short bed frame

 

Is the only differences between these two frame, is the steering box is mounted on the outside of the frame on the '80 one?

 

And that they use the same a arms and ball joints.
