will a rear seat out of a 70 cutlass supreme hard top fit perfect in a 70 cutlass convertable??? or are convertable and supreme hard top rear seats different?? THANKS

MDchanic

A-body convertible seats are narrower than coupe seats because of the extra width of the top mechanism.

Any 68-72 Chevelle, Pontiac Tempest, Olds Cutlass and Buick Skylark series convertible will have the same rear seat.

A Supreme has rear armrests the same as a convert, so I would think that the seat would be the same width...I am not going outside right now to measure any

Here is a convertible back seat:



Here is a Coupe Back Seat:



Notice how the top mechanism intrudes and makes the convertible rear seat smaller.

Notice that the Supreme coupe has fillers and armrests the same as a convert, thus making them the same size...I am not going out to measure them right now thanks...

I have always believed that the seats were different sizes in spite of the stamped steel filler that goes from the plastic armrest to the rear shelf, but I will admit that I never measured them, even during the many years that I had both A-body coupes and convertibles at the same time. Now, with an A-body coupe and a B-body convertible I can't go out and measure them.

If someone else here wants to go out and measure them, or has a parts manual that would confirm the part numbers are the same or different, or can say that they have interchanged them without modification, that would settle this conclusively.

I have always felt absolutely certain that the seats are different sizes, but I would be glad to admit I am a bone-headed moron if, in fact, I am.

Try it!! Then you'll know for sure!
What do they weigh - like 10-15 lbs.??

The above information is pretty clear as to interchange however here's info from an Olds parts manual.

70-72 f85 convert series 4267 rear seat back springs part # 9615772

70 f85 Cutlass Supreme 2dr hdtp series 4257 rear seat springs part # 9615771

This refers to the upper rear seat back.
You might also mull over the fact that all repop rear seat covers will show converts to be unique.

I took it myself, in September of 1987.

A buddy of mine drove that car to college from California his sophomore year.
It was painted pink with a roller.
He passed it on to another guy, that guy blew the trans and gave it to me.
I put it up on blocks and changed the trans ($75 from Charlie Molt's junkyard), then drove it for another year before the engine blew.
It had no top, so I had to wear a poncho if it rained.
It also had a high compression 350 and went like a raped ape.

I was driving a 911 Targa at the same time that year, and, let me tell you, the Cutlass was a whole lot more interesting to the girls than the Porsche was.

a pink convertable LOL!!!!!!!!!! i wish you still had it in need the back seat

Ok; So I went downstairs and measured an armrest for a '68 Supreme @ 3"...an armrest for a '68 convert measures @ 3 5/8" or so... so it seems I am mistaken again then in the parts book Supreme rear bottom cushions are alone '68(7712580) as are converts '68(7788607)...so the converts must be narrower by 1 1/2 inches than a Supreme...shoulda looked in the book first '70 convert rear cushion # 9812344 ....can't find a listing for a '70 Supreme

MDchanic

For us (and the college administration) it was THE Pink Convertible...


You wouldn't have wanted it. It was in the weather for years.
The car had practically no interior, and not a single good body panel.
