I swapped mine too, I think it made a big difference. It's not power steering easy by any means, but much easier then the stock gear box. To keep the '37 steering wheel, I cut the shaft on both boxes and welded the '37 top to the '41 lower section. If you choose to keep the '41 steering wheel, you may find the wheel offset a little to deep. This placed the rim of the wheel a little closer to you gut. All in all, it's still worth the trouble.
