Ball joint taper

[Geoff]

Hi All

I am using a Ford Transit Van drag link (Quinton Hazell QDL1117RHT) as the top ball joint on the front suspension of the 40.
Can any one please tell me what the reamer angle should be?
Some other sites say 7.15deg but that is not what I am measuring on the ball joint but I may not have the measurments correct as it's not easy to measure.

Also where would the best place be to buy a reamer?

Thanks for any help.
