Does anyone know if the core supports are interchangeable
between the two years? These are for Cutlass/442.
I had a friend ask and I didn't have an answer for him.
I waded through the search option and didn't find it.

 

Pretty sure NO they do not interchange.

 

They interchange except that you have to use the same year headlight setup and grille. If you use a 67 support and headlights, then you have to go to a 67 hood, and fender extensions (they are longer than 66 extensions). If you use a 66 support in a 67, with 66 headlights, the hood looks odd because it is "cut out" farther for the longer 67 setup.

 

So, the answer is, the core supports do not interchange. The whole nose interchanges as a unit, just like on the 1968/69 cars.

 

I have the 67 'frame and latch assembly' for 67.
I have the headlight frames & buckets for 66.
I think the steel insert that sits below the buckets that runs
along the bottom may be different for the 66. But that piece may be
interchangeable between the two as it is a bolt on unit, no?

Trying to build a 66 out of parts from two....recycling I guess.

 

The core supports and all that bolts to them is totally different would be happy to email anyone pictures who needs them of what is different.

 

Larry, thanks for your input. You saved me from banging my head
against a wall.

 

The two years supports bolt to the frame horns in the same way, and to the fenders in the same way. Thus, I said they could be interchanged on the car, but making them work properly is another story, as has been elaborate above. The end result is this: get the correct year core support for the car.

 

Why not just buy my 67 442 and finish it so i don't have to dig up all the parts! It is a post car with very nice body! No motor or tranny. I have a 455 with fresh crank.main bearings,rod bearings performer intake can hear run with ga heads! I also have a turbo 400 unknown condition that i could throw in. PM me your cell # or web address if interested. Thinking of selling because i want to get my tube chassis 1970 442 finished or i may sell the tube chassis car to fix the 67 442.

 

I am trying to RID myself of a few projects. My son is going to let his
66 go, because he found himself a 66 442 project that will need some
things from That one, and my project core support was for it. He has
already finished his support and it will go for the 442. Confused yet? Ha ha.

I also need to make room for the 70 442 coupe that will be coming to my house in the next few months. And let's don't forget about the 69 442 coupe.... Friday, a fellow is taking the skeletal remains of a 67 for the frame. Hate losing that 330 crank, but it's all good.

Thinking about selling my cruiser, yes the red vert...Any serious interest
in that one?

 

Agreed, but to me that's not the definition of "interchangeable". I would consider the 71-72 core supports to be as close to interchangeable as possible (yeah, I'm aware of the differences between the two). You could put a 72 core support on a 71 with no other changes. That's not the case here.

I will say, however, that the 67 core support, at least parts of it, appear to be the same as 66 parts. The area where the headlights attach is the same. The 67 just has these additional horse-shoe shaped brackets that support the inboard end of the wider headlight bucket assemblies. Remove those and you can probably bolt 66 headlights directly to the 67 core support.

 

The 66 support has two round holes for the two headlights on each side. The 67 has a round hole and a small rectangular hole for the parking light on each side. The inner headlight "hole" is the inside of the stamped steel "loop" to the inside of the sheet metal "baffle" [as Olds parts dept. called them]. So, yes. I guess they should not really be called "interchangeable" for the reasons discussed above.

 

Rather than mix up the wrong parts find the correct ones. I can do a 66 core support and a 67 core support for anyone needing either. Plus the bolt on pieces.

Here is a 66 and 67 core supports. You can see way different. The first one is a 67 laying on the ground and the second one is the 66
