Done a few rufs on suzukis, one moving the hangers foward (works great) and one just makeing big long hangers (not good) but now just heard of the boomerang shackles witch puts it right for ruf.
Anyone used these i reckon they would be the gos.

Also wouldn't mind some diamentions of then so i could make my own instead of 50$ a shackle on trade me

No its a stupid idea. You could make the shackle an 'S' shape for all it matters, what counts is the distance between the bolts in a straight line. The only proper and safe way to do it is with a chassis extension.
