Bob Drake has a kit that replaces the reflector and uses a halogen bulb, I THINK an H4 bulb. His kit uses the original lens. There are replacement LED bulbs for the H4 bulbs. A round-about-way of getting there, but worth a shot. His website says the kit is out of stock. Maybe some of the vendors who sell his products have some in stock. I have his kit on my '38 and the focus is good. I have read reports of kits from other suppliers that aren't focused correctly and the light is scattered.
