Batboard

I have a donor astro spectra W4 dash mount with a working head, I'd like to pick up a remote mount astro spectra (with no head) that has the same codeplug and s-record as my dash mount. Between just the two radios will I have all the necessary interconnect boards and such to do that swap?
I'm aware converting from dash mount to remote mount requires extra parts, but it seems I should have everything I need in this situation.
Thanks.

I know there are some serious experts on here, can anyone chime in?
Thanks
