Nope, it can only tell you for sure its NOT a W31. VIN needs to have an M in it as all W31s were made in Lansing. VIN would be 32770M
3277 F85 club coupe
3677 Cutlass club coupe
3687 Cutlass hardtop coupe
0- 1970
M - Lansing
3277 F85 club coupe

uh, duh, my fault you are correct, I was thinking W30 but its the same for a W31 you can only tell if it isn't. Everything else can bolt on
#6 cyclinder heads
really thick harmonic balancer
W25 hood
I'll edit the post above so it should be

Do you know if it was a special customer order? Usually the red/white exteriors had a white interior, although black works too. Are you going to put wide body stripes on?
#13
yes 10A would be October first week and since its a 1970 car it would be 1969
and yes I thought B was Black top - A is white

That's why I asked about what I thought was a 'wierd' color combo. Makes a lot more sense now.

So it's a fastback 442 coupe that has a black interior
#23
There are the remains of one in Canada,with documentation,that is Matador red,with a white top,but has black stripe & black interior,or maybe its the other way around.I know the top color was different than the stripe & interior.
The W31's came with the normal Cutlass bumper,with no cutouts,but many have been changed since then.The W31's did not have any type of undercoating or sound deadener either.The #6 heads for the W31's were hand-picked from select castings,and were given the larger intake valves.ALL W31's came with manual disc brakes,and NO AC.You could get the W31 in the F85 post coupe,the Cutlass 'S' post coupe,or the Cutlass 'S' hardtop.The only true way to prove it is a W31 is with documentation,which isn't always with the car.

That is proof that it is a W31.
#26
Yes,you could,BUT I have a JO TH350 trans that I removed from an original 70 Cutlass,built in Lansing,and that car was NOT a W31.How did it get installed in there,not sure,but the VIN on the trans matched the car.It was a plain Cutlass 'S' with the side moldings,power drum brakes,no AC,2:78 open rear.I can't say how many other JO's wandered into other Cutlasses,but I would think not very many.
So,what do you do if it is a 4-spd?

"The W31's did not have any type of undercoating or sound deadener either." That was my understanding as well, but I was questioned at the Nats in Reno about my lack of rear wheel well undercoating on my restored W31. I did not lose any points, but it got me wondering if it was only the sound deadener that was not installed on W31's. What about rear wheel well undercoating?
#28
Brian, I have also heard of the "JO" trans being in a regular Cutlass. The W-31's did not have under coating and the wheel wells had no under coating. Further, there was minimal insulation under the carpet. The only insulation under the carper is on the front floor board.
If the W-31 does not have the original paper work, then, it would be difficult to authenticate.
I believe a person can inspect a w-31 without documantation and state with confidence that it is a w-31, but that confidence rate may not be 100 percent.

Please explain. What documentation do you have on the bumper? The bumper could have been dealer installed, but that means it did not come from the factory with it. Unless you came offer some proof that it came from the factory with it, I have no reason to believe that it did.
#34
It is easy to see why a new owner would want to have he cutout bumpers and trumpets. But they didn't come from the factory with them. I'm reasonably sure that at least a few dealers did the installation.
But the W31s by and large were not bought for looks.
#35
lol thats the main reason i pestered my uncle for his car for half my life was just because it looked cool. it and the rallye 350 too. just too bad i couldnt convince him to hold on to his 68 hurst/olds but he sold it to a guy that had just came home from the military so i think he deserved it.
