69 Dart trans crossmember

Getting around to detailing all the parts for reassembly for my bastardized dart. It is a 69 Dart which will have a 340, a later spool type K member and a A-833 OD transmission.

Which trans cross member do I use?

I am not able to mock up the engine and trans right now. I have both the early and later cross members and am pretty sure I'd use the early one (match the car) Right??
