email sent to Boese asking about it and here is the response:
This dash inserts bolts into the stock bezel (this is all that the blue piece is). I don't know of anybody who is reproducing this bezel for the
60-63 Chevy Trucks. We picked ours up at a swap meet for $15.00 & just threw on a coat of paint.
I'm assuming that the bezel & gauges are gone from your truck. I have seen the bezels on ebay, but only with the stock gauges as of late.
Thank you.

so there it is from the horses mouth. Thanks Dean for the quick response. guess i'll try to find a cheapie stock gauge on ebay to hack up.
