The trans lines up surprisingly well with the halfshaft tunnels, I have a bunch of photos as I went along and was checking the alignment, I will have to dig up the final one.
This was one of the very first ones I took, before I moved the engine aft - you can see how far forward it looked like it sat. In the final position the tunnels line up almost perfectly with the bore in the case for the inner drivers.
First mounting position too far forward:
Luke,
You can see in this picture that I moved the whole thing back about 1.5" from the one you posted (I have since cut the tube off and made another plate so it fits right, but you get the idea how much farther back it moved).
I am embarassed to say I haven't actually even thrown the radiator back in yet to see how it fits, I am sure the original one would fit, but I was planning on using and AL core C900 radiator since there's a stack of 20 of them in our parts shed, or maybe even one from a 9-5 or something, but I do need to double check how much space there is. I need to make sure there's enough space to add an intercooler later too!

I absolutely agree with this, you summed it up really well in that one sentence right there.
This is a really big deal with professionally designed race cars, with seating position, ergo, controls interface and control forces, all that stuff. There are some really cool vehicle ergo books that are mostly based off research done by the government for jet fighter cockpit design in order to maximize operator response and concentration.
This was thankfully something I was exposed to fairly early with the FSAE competition I did, since everything is custom made and fitted, and one of our team member's was really into it. One of the cars I built used a 450cc single cylinder sport quad engine ridged mounted with steel supports right to a steel tube frame car. It vibrated a LOT. You got pretty rattled after a stint in that, but the vibration wasn't really what got to you - it was actually the steering being such high effort, but something that a lot of teams with the single cylinder engines run into issues with is their motor mounts fracturing from all the vibration.
Best,
Drew
