they will fit, but the clocking of the outlet flanges may be different, as well as the head pipe size increase. i don't know if 68 head pipes will fit your 67, or you will need custom bent pipes.

As said outlet clocking may be (90 deg) turned tho that might be a C body thing. ports/mounting would be the same & the only other potential difference could be the location of the vertical down outlet. at worst just different head pipes needed.

Everyone I know uses 67 440 hp manifolds on a 67 - one year only. I don't believe 68 will work well. I have both on the shelf. Will try to take a picture of them side by side later tonight.

Pasenger side is the same part number. Drivers side is different part number, will fit and work, but the pipe on left side is different clocking, same 2.5" diameter.

This. This will either require a 68 head pipe, or possibly a custom one.

I think TTI can set you up with a head pipe that will work.
