Default Putting 68-72 removable window in 75

I am retrofitting the rear window in my '75 to the 68-72 style removable window. For anybody that has the interior of their 68-72 coupe pulled apart, I would be interested in how the two lower plastic pieces are attached to the body window frame, are there speed nuts clipped in there or do the screws go into the metal frame?

Thanks, Scott

I have that section out of a car that I scrapped...so I can take photo and post it tomorrow...unless someone comes in and posts one first.

I can say you are in for a bit of a fabrication 'party'..and it will not be as easy as it seems. And that depends on how correct oyu are going to try to make it when completed.

i did that swap to a 76 many years ago. i pulled all the parts from a wrecked car. i don't remember any difficulties or details for that matter. but i remember it being quick and easy.

Hi Scott,
I'm thinking there's a 'tapping plate' under the sill to receive the 2 screws?
Perhaps these will help.
Regards,
Alan

Thanks for this. From what I can see I need to drill an extra hole for each latch to match the existing hole. My car has a speed nut there but I don't think it was ever used. Can you confirm that there are speed nuts that are used to mount that hardware?

The current state of the lower rear window frame on my '75.

Hi Scott,
There's a rectangular tapping plate under the fiberglass 'sill' that's held in place by 2 rivets.
Regards,
Alan

How does the window fit into the space and what holds the top and sides in place?
Are the window openings the same?
Can you use your rear window or do you need one out of a 72?

Hi O,
The glass for the removable rear window is set in a polished aluminum frame.
The glass is held in place by 2 'pegs' attached to the bottom of the frame... they fit in the 'receivers' shown in this thread...and 2 spring loaded latches across the top.
I'm unsure but I'd think the glass is a different size than the piece for the later fixed glass.
There is also a fiberglass tray that's mounted right below the rear deck to store the glass in when it's not in place.
Regards,
Alan

Interior side of window.


One of the latches.


The pegs.




Glass/Frame in place.


The tray morphed over the 5 years from a flocked fiberboard tray to a fiberglass tray.

I did this in my 76 last year, not hard if you have all the parts, I did and it was just a lot of taking off my old parts and putting on the older parts. You can either have the correct roof panels or cut up the ones in the car. IF anyone wants a window tray with all the parts to install it, I have one that is like new, with all the parts to install and the old car's bulk head with the screw holes in them to show where to drill the holes correctly. Pm me for price. I hardly put the rear window in now, just leave it at home, GOOD air movement thru the cab with the tops out or not.
You do need a new rear window gasket, it is different than the existing window gasket, that was the hardest part to install, it usually is a little larger than it needs to be, when installing.
