Interchanging A904/A999 Tail Housings

Hi,

I'm in the need of a tail housing and searched eBay. I found a few late style housings. My question: Will the early and late style extension housing interchange with no issues?

Thanks in advance!

Might need to be more specific as to where your case comes from. 904 and 999 case is the same so the tail shaft housing from any 904 will work. Unless you have an RH version from a non pass car application.
