Found different window guides in doors

I pulled all my door peices out of storage and was getting them all cleaned up and rady to go back into the doors. I noticed that the window guides were different.  This cant be right, can it? I was looking through my paddock catalog and all they show is the larger and square style for replacement, so i am not sure what i have on the one side.

Wow, i cant believe i couldn't get anyone to figure that one out.    Actually i got it figured out. The larger rail style, with the square looking guides are for a 70-72, and the skinny rail with rollers is for the 73-74. I guess i get to buy 2 kits now.
