A body quarter window question
 

Are the A body quarter window the same? Thanks Steve

for the GM 68 - 72 years

Rear Quarter Glass:

'68-72 Pontiac A-body 2 door HARDTOP only interchanges among those 5 year Pontiacs.

'68-72 Pontiac A-body 2 door COUPE (2 dr post car) interchanges with '68-69 Chevelle 300/Malibu 2 dr post.

'68-72 Pontiac A-body Convertible interchanges with all '68-72 GM A-body Convert

tracks yes, glass no. if you're talking Lemans/GTO hardtop yes, 68 to 72. cutlass, buicks and chevelles had different glass.

A body convertibles shared quarter glass 68-72 across the GM models, and are different than the hard tops.

OPH beat me to the enter button while I was typing!

I have a 70 GTO.

it is a hard top

From the 68 Fisher Body Manual

I would have never thought that there was that big of difference. Thanks for your post. Steve

Years ago, laminated a copy of that illustration, have it handy out in the shop.
Have sold a lot of nice unscratched late 60's, early 70's A-body factory tinted rear 1/4 glass & door glass out of partscars. '69-72 GrandPrix rear 1/4 glass has been a frequent pull here & I've ran into it at swappers & in parts cleanouts mistakenly tagged as "GTO" <wrong>

The intro of the 1970 model A-bodys also brought the following new variations of rear 1/4 glass:
- '70-72 Malibu-Chevelle/Skylark-GS hardtop
- '70-72 Cutlass Supreme/MonteCarlo (have parted a bunch of these)

I am in need of RH and LH rear power window regulators. I have motors, harnesses, glass, etc. I have dozens of motors, probably 4 full sets of manual regulators and harnesses, etc if anyone has need for such parts.
Any advice?

Be careful if you are using used glass. Even though it MAY interchange you might have a window felt rub line in the glass.
Found that out the hard way….
