I attempted to install the bell cranks. The instructions call out reaming the weldament to accept the bushings, but they really don't say HOW to do that or what the required tolerances are. I had to send off a support request to Vans. This is probably obvious and not a critical dimension, but I prefer to get their feedback.
I moved on to fabricating the push rod tubes. Measure twice/cut once. I left them a little long to allow the hacksaw cut to be squared up on the disk sander. They came out great - right to the specified dimensions.
