Can I mix Chrome and black?

[Fatso]

Hi, Im a new member here and a new owner of a 203fe. Somehow I ended up with a late model 203fe black and an excellent condition film back in chrome.
Am I going to have problems if I use this combination together?

No problemo for diffdrents collors. smart to have one body only and different color for back to remember what kind of film you put in witch back.
