Once you swap transmission, scratch out L43 on I’d plate and put W50 somewhere close to it. This way any future owners will know it’s not an L43. A drywall screw works great for doing this.
I'm using the plate for my w58 swap. I was going to mod the original Xmem but it wasn't gonna work as I wanted. I still need to machine the holes into it but when I'm done I suppose I could ship you Xmem too....
I'll give some thought to the crossmember. It would make my life easier and require no fab but would also mean shipping another big item across country which is worth it for a trans but not sure about the xmember. Let me know when you get the shipping box together and I can pull the trigger on the quote. I'm also going to check Fastenal as a buddy told me they also have a good shipping system, is that closer or further? Because if it's less convenient I don't wanna make things harder.
