BANJO Center Housing Dimension Needed

[V8COOPMAN]

.

Does anyone have an empty '35-'48 BANJO center section like this laying-around that you could easily get me a fairly accurate dimension across the open face....OUTSIDE to OUTSIDE? Inside to Inside would be handy to have, too.
Thanks in advance, guys! DD
