if your going to use the rotators they come with the 5/32 holes for the stock struts to fit,for these I made my own connectors and they seem fine for strength, would have prefered the 3/16 but they are not making the units now with that hole size so I ordered the ones they had at the time.

for the units that I have in my Mustang I went for the larger wire connectors, since I am using the larger Robart 662 struts and they don't use the smaller wires anyway, the smaller Robart struts come with a adaptor for each wire size.

when I made my connectors out of regular piano wire stock, I heat treated the metal after cutting for length, surprising how hard the metal gets when red hot and quenched in water or oil, it increases the brittle nature of the steel but it won't bend without alot of effort.
