Thanks for the responses, my thinking was not to ship a complete axle, if the axle were damaged or bent ( not worth fixing ) then the parts that hold the perches could be cut off and shipped in a flat rate box, the only other option if you wanted to was to have a machine shop press them out, let me know what you want for them.
Drew, ..... here is a pic of the AA perches ..... just in case you are not familiar with the fact they are different from the car perches.
