Truetrac Spacer Axle End Play

I have installed a Truetrac diff my s-10, now that the cross pin has been replaced by the floating axle spacer, the end play is doubled...and it sucks! I need a wider axle spacer, but Eaton says they can't help. Does anyone know the diameter of the S-10 26 spline 7.625" axles? I can get a new spacer made, but I guess I'll have to tear my diff open, measure and take the spacer out to get it duplicated but slightly wider. Here is the spacer I'm talking about: http://www.superchevy.com/technical/engines_drivetrain/driveshaft_rearend/sucp_1007_gm_12_bolt_rear_end_rebuild/photo_18.html

Welcome to the forum. I don't have my numbers in front of me, but I'm sure someone will chime in after not too long. Really wanted just to say hello and say that's a good first post. We're all big car whores around here, so we'd love to hear more about your ride, maybe even convince you to do a project thread about it.
