the bait clips which are on the weight its self?

im making my own weights just got aload of lead and moulds so could use the loop with the bait holder

The impacts slide onto the main rig body,then another weight link is added for the weight but some anglers just use a weight & bait link in one as can be seen below;

Usual weight & bait link;



Impact shield then a weight link for the weight;



Are these the eyes your on about for the weights?
