Lead screw coupler

[mailman]

I have a sidewinder cnc, bought it last Sept. thought I could get it going, so far all trouble, I noticed my lead screw couplings are all cracked, I am sure this is causing my axis to slip. I am trying to contact company where I purchased the machine no answer, I don't know if he is on vacation or out of business. Where is the best place to order new couplings, I think they are 1/4 x 1/2 about an 1.5" long. Thanks, Mark
