Welding is most likely not a viable solution, it's just aluminum.Mine was cracked in one spot on the left side near the left fork top bolt. Looking at what it's made of, I don't think these can be welded?

Would you happen to still have that top tripl tree?I have an extra clamp. I was a bit overzealous when I removed the paint to polish the clamp. No damage other than a few wire wheel marks and heat blisters. It is a bad pic, but you can see it on my 1973 K6. Although the gauges on the bike are aftermarket, the top clamp is original to the bike. I would be looking for $45 plus shipping. Pm me if interested.
