1941 was fist year for the better gear boxes, so no real need to up grade to the '38 other then a little better ratio. I cut both steering shafts, the '41 and '37 so I could keep the '37 wheel and horn assembly. The '41s have a slightly different steering wheel offset which put the wheel to high and to close to the driver, adapting the '37 shaft was a matter of measure, cut, and weld so the interior still looks and feels like a '37. I also have a adjustable drag link, its super handy to center the gear box and make slight adjustments as needed. I changed from 4 degree caster to 6 degrees and the steering wheel moved a little more then 1/8 turn off center, I pulled it back with a turn of the drag link bar.
