Having headshell custom built - need dimensions

[rippingrudy]

Hi,

I'm having a headshell made for my Lonestar Classic (the older 50/100 watt version). It is currently a 1x12 combo but I'd like to use it with my 2x12 recto cabs for the summer.

I'm wondering if anyone has the dimensions of the chassis already spec'd out?

Thanks
