Alright. I got a butt lift.
I took a calculated approach that's likely to disappoint most everyone here. I had two approaches, one was ~$1k and 2 days and one was $5k and 2+ weeks. I knew the second one would make it all perfect. But before I did that I wanted to give the $1k option a chance. I took it to Bugformance (the local VW Bug experts) who shared they saw this problem before (as mentioned above).
After seeing mine they now believe this is a flaw in the way the frame horn was weakened for the heater tube. I was open to Kafer bars and the like, but they seemed to think this would hold up far better than it left the factory in 2006.
Exhaust looks level. A bit scared to bring out the actual level.
They made a point to show that not only was the crack welded up, but also the seams on both sides of the frame horns. And then it was patched over. It looks like the did a fine job to me. I think far better than the other one turned out 10 years ago.
The ride home was uneventful. It was good to be back in the Speedster, but I was nervous to reacquaint myself with the car. My accelerator still is "sticky" and had hoped it would magically be cured at the same time as the butt lift.
And, the engine compartment is as sealed as I've ever seen it. Really. It looks like a brand new engine compartment. I'll get pics later.
But what do I know? What do you all think?
