I was going to make some of these up in the Lathe. Does anyone have any dimensions?

Total length overall?
Length of external thread
Depth of internal thread
Diameter of the bar?
All in mm please, as I find the old stuff hard!

What rack, uprights and wishbones are you using?

That may dtermine the length etc for the extension pieces.

escort mk2 rack
+25mm (per side)front wishbones
cortina mk 3/4 uprights.
