@1Ton Tommy: I had that thought (replacing the crashbox with a tranny that has synchro). I imagined there was a difference. Good to know.
I'm happy so far with the crashbox. I haven't done much more than testing it in the driveway. I think I could stay with it... there is something about the sound and feeling of driving a vintage truck... nostalgia I suppose. But I can also imagine myself getting sick of double-clutching, grinding, etc. But who knows.
