Good points Stan. I actually did miss that Adrian suggested the HCT part, good idea.
In looking at the HCT part, it's current outputs are pretty low, maybe a larger resistor on that LED...
Lead spacing for the resistors is .5"
Lead spacing for the caps is .2"
Lead spacing for the diode is .4"
Here's the board with what should be all the dimensions you might need, including the connectors, the pot, etc.
