Those look like the ones I used, well similar to them. Not sure if they were M3 or M4 though buddy.
On a side note, you may can just heat the ones that are on there, with a heat gun, and tweak them a bit.
Glad you are pleased Griff.
I used some ends that I had from a Wraith kit I believe buddy. They have just a slight angle to them, think it was for the upper links on the Wraith.
