Thanks very much for the kind welcome. I must admit I was quite thrilled with learning that Morgan had resumed production of a three wheeler, and also in that it seems to have been done very well, especially the styling. I love it. Can't afford it, but love it.
I'm afraid I can't help with the DC-3 mod :-/ To answer your question, asbojohn, I've made the centers to my wheels to mount to the bolt pattern of the supplied boss, but added three more holes for a better look. Those holes can be used with additional drilling of the boss, or just plugged with the tops of identical screws (like what PaulJ did). There may be an additional opportunity to use more interesting methods for fixing, like flat head, polished bolts or even riveting.
When I look at this car, I see an excellent job of having made the car look like a convincing classic. However, the steering wheel falls down in that regard. This is a common mistake made with all types of replicas with one good example being the popular 356 Speedster replicas. I've even seen some expensive replicas of more exotic cars like early Ferrari's with simple Moto-Lita wheels. Ughh. Please understand that I am a steering wheel snob, and as such have some very definite opinions based on the historical appropriateness of a wheel design for any particular car. I will also acknowledge that my focus is much more on what looks good than and concerns for reduction of size. That's because the steering wheels of past were larger, and the farther back in time, the larger they were. PaulJ, I will resist saying anything about an 11" wheel, but I think you know where I'm coming from... or did I actually just say something about it?
I believe it would help to look back at cars with cockpits of this nature to get an appreciation of the types of interiors, dashes, and wheels. There are many excellent examples. I have taken many pictures of my own and borrowed others. I'll have an eye out with special attention to these when I visit Amelia Island in March. Here are two great examples...
Both are Maserati, the second one I'll be making, and already do for the Sprite. Here is another, although only a mock-up drawing at this point:
There is another wheel that I think is a good choice for the M3W if only because it has some Morgan provenance; the wheel used on TOK 258 at the '62 Le Mans:
