i would say the 3ge ones are well made better job than i could have done not haveing a cnc or lathe in my garage the problem is the draglinks on the market very slightly (i know i had 2 diffrent makes) fine for use on an old mk1 transit as a drag link but you have to remember we are not using it for its designed use
i have 3ge mushrooms and qh draglinks and i had to ream my taperd hole just a very small amount with the reamer i used for the sierra uprights to fit maxi ball joints and then shave a bit of the hight to suit the link only about 1mm
must have taken me all of 20 mins to do the pair
