Recently I was in contact with HM Engineering to order some new pins for my HD UCA's. While talking with them they told me they still had some HD UCA's for the Commander in stock but nobody to sell these for them.
I jumped in to make these available to others in need of some more Heavy Duty parts.

Currently I have two sets at home ready to be shipped and an other six sets coming in the future (have some missing parts which are being fabricated as we speak).

These are the exact same HD UCA's GetLost4x4 used to sell on the "other forum".

I sell them for USD $575 shipped within the US. I will ship worldwide but higher shipping cost are involved so PM me for shipping rates outside the US.
They come with stainless steel pins and grade 8 nuts (see pictures below).

PM me for more information.
