Unitrack conversion section

Looking for some help with the Kato Unitrack conversion section. I am using N scale and wish to join Atlas code 55 sidings to the uni mainline. I am having a problem getting a N rail joiner onto the rail on the conversion section. It seems that the Kato rail is code 80 and won’t line up with the Atlas c55. I have filed the converter rail to try to match it up and still have a problem. Has anyone out there ever done this, successfully, and what did you do? Thanks, SFBill

If memory serves MICRO ENGINEERING make transition rail joiners for code 55 to code 80.

I cannot be certain, it’s rare for me to think this small. LOL.
