Stupid me overtorqued my 66 98 drivers rear quarter glass this evening and it shattered. D*mn. etc, etc, etc.

So I need to figure out what fits to find a replacement.

I'm 90% sure convertibles from 65 and 66 are different from hard tops, but not sure if 88 and 98 convertibles used the same rear quarter glass.

If the 88 and 98 glass is the same, that rules in all the B bodies (impala, wildcat, etc) and expands beyond the C bodies (Caddies, 98, Electra 225 and the Catalina.)

Also 67 seems to be different from 66's, but I need to dig further to be sure.

Anyone have a line on a driver's side rear quarter glass (or both sides) from a 66 98 convertible?

Thanks,

Sorry to hear that. I'm sure the "etc." was pretty interesting to hear.

The Parts Manual shows 4462908 for both '65 and '66 98 (but not '67), but 4462911 for the 88.

I do not know whether that is a "real" difference, or something superficial.

Good luck!

The C-body cars have a longer wheelbase than the B-body cars, and that length is all in the back seat area, meaning that the quarter glass is different.

I only ever had B-C four-doors, so I never knew that that part of the 2-doors was longer.

The length difference in the rear doors was always obvious.

Thanks, Joe!

edit: on further reflection, I realize that I had not known that the 98 convertibles in those years were true C-bodies, with the longer wheelbase. I'd always just ASSumed that they had 98 trim on the 88 frame.
I'm a bit impressed that GM took the trouble to make two different convertible frames for that model line.

Three years later I found the right glass from Desert Valley Auto. $125 or so shipped. Very fair, I thought.

What I learned along the way:
1) 1966 Caddy Deville convertible glass is shaped differently at the upper rear corner than the 66 98.

2) In 66 Olds bolted the glass into a steel frame with rubber insulators to mate to the regulators. By 1968, they’d shaped the lower portion of the glass to eliminate the steel portion by riveting the plastic rollers directly to the glass. This is part of the reason ‘66 and ‘68 convertible rear quarter don’t swap in the interchange books.

3) With modification of abuse of the inner steel car body and cutting of new regulator channels on the inside of the quarter< 1968 glass can be made to fit, but not really well. I used it this way for 3 years, but to was never quite right.

4) This spring I installed glass from a 1966 Buick Electra 225 and it fits perfectly. So there you go, 98’s and Electra 225 glass swap!
