My C-67 Enlarger won't align with C700 and C760 lamphouses

Everything I've read online says that the C-67 enlarger should be compatible with C700 and C760 lamphouses. I have both and while they fit onto the enlarger the opening of the lamphouse is misaligned by a quarter/half inch making it impossible to print a full 6x7 negative. I thought it was just me until I realized that they both don't line up.

I also have a non-working Super Chromega C Dichroic which aligns perfectly. Its very fragile plastic sliders and giant power unit make me reluctant to try and replace this one.

Am I doing something wrong with the newer lamphouses? What could the problem be?

I would ask KHB.
The C700 and C760 are of course more recent. Maybe your C-67 has been modified in some way.

I had a look thru my pile of manuals and found the C760 manual. There does seem to be an adjustment for the position. I'm not sure how far it can be moved. The instructions are not the best but it seems loosening the hex nut on the adapter will let you move the lamphouse a bit. Let me know if you need a quick scan of the pages.

Could you? That would be great, thanks!

Here you go: Omega C760 A little too big to attach.

Thanks for sharing, I found where they discuss alignment with C67 but can't figure out what's moving to align. I'll try it again
