Which is which on these windows?

So the other day i stripped out the doors and found them a little different. the Rt one has 11 holes and the Lt one has 9 holes.  so which is the 70 and does it matter?

thanks

If I remember correctly, 11 holes is 70-71 and 9 holes is 72-74. The extra holes are for access to the up stops. Either window will work no problem. Bigger concern is whether the outer window fuzzies attached to your doors differently ? is your one door newer then the other?

nope.   both doors are the same and original to the car..  was worried that without the extra holes i might have some issues when it comes time to put it all back together and make it work properly..

thanks

No worries there at all, you're good to go

Also, there glass has date code on them if you want to know exactly what year it was made. Look for the small etched logo and post a photo of it.
