Even though I just dropped 6300 total on a 2.2 WBX, I'm in agreement with
you, Stuart. I'm hoping to sell this rebuilt WBX off within the next year
or two and put in a more modern power plant. Feels like I wasted money, but
I had to get the bus back on the road. Any conversion I'll be doing myself.
