Ø.105 gage pins are available from MSC #89010508 @ less than 3.00
The rest of this is probably more information than anybody needs.
The pinion gear deails are: 16 DP, 20°PA, 18 Tooth, 1.125 PD.
I have measured the layout of the crank and cam locations on 1 set WR cases and 2 WR timming covers. they agree with those made by WR racer who is also another tool maker that I trust and the locations agree within .0005".While I have not checked the PD of the gears, the center to center distance of the gears is .002-.003 larger than the distance if you use standard pitch diameters on the gears. This will give you the backlash which is designed in. Keep in mind that these were measured on WR parts which may have been manufactured to tighter tolerances then the street models.
When measuring the gears the dim. over pins does not take into account wear. Axtell actually lapped the gears together to get absolutly free running, or different tolerances due to cheap repop parts.
It this blacklash actually the cause of the noise? I'm not 100% convinced.
Probobaly these locations were done on a drill press using a reamer and drill jig, which could wear over time, but I'm stil not sure that a .005 or so backlash in the gears would cause a lot of noise.
What do I know, I race an enfield and you can't talk over the valve clatter.
I will measure some gears when I get a chance (i'm getting ready for Wauseon and Mid Ohio). I'll also calculate what the dim should be over drills.http://www.enfieldracing.com
