Window door glass guide question

[Dragon383]

I am looking to buy a passenger side window door glass guide (the channel that keeps the window in track).  I am looking at classic industries parts ME8149.  My issue is that it says first it is only for a Challenger and second, that they were all the same from 70-74. The ebody window hardware changes between 72 and 73.  I know this because my door has the earlier style channel and I need the 74 guide that is narrower.

Is the book wrong and there are two different guides in challengers? Or is the book right and challengers had the same guide for all 5 years? 

Any help would be great as I would love to have a passenger side window again

Thanks

Your assumptions are correct...the book is wrong

Thanks, that is what I figured. Anyone know where I can get a correct '74 passenger side window guide?  Classic Industries tech help is worthless.
