Hi all,

I have used an Omega D2 enlarger for over thirty years. I recently bought, and just finished restoring, a D4 autofocus enlarger and thought the D2 carriers would work on the D4. It is now apparent that D2 carriers will not work with the D4 because the D4 film stage has no carrier locating pins. I have a small machine shop and could put pins in the D4 stage but don't know if that is the best solution. What are the differences between the carriers and their locating features? Any suggestions will be appreciated.
