[Closed] SS Chains - Half links & SRAM PC7X?

I need to get rid of the tensioner (held on by zip ties), so I've now got a nice looking Forward Components EBB waiting to be fitted. From the sag on the chain at the moment I reckon I'm going to need a half link, so here's what I need to know:

Will a KMC 1/8" half link fit to a PC7X?

Does anyone sell spare powerlinks for the PC7X?

Does anyone sell both PC7X & half links - can find one or the other at many sites, but not both?

Any alternative to the PC7X?

Can you get half links for track chains? I've got one of the NJS chains on at the moment but they're a bit thicker than 1/8" I think (PC1 powerlink doesn't fit).
