bad parts

Can you tell me where/how to get replacement parts for bad parts in jyetech scope I am building. The kit looks okay, but one of the st3p sliders and 3 of the pushbuttons did not work at all. I am assuming they were defective. The slider would not slide and while trying to free it, it snapped. They can not cost much, but finding the parts is hard. I do not see the sliders in your parts section. So can you supply replacemets, or tell me where they can be found? Thanks?

Please email us your order number, we will ship replacement to you. Thanks!

The replacement parts arrived.
