Hey guys! The later pinch bolt style ball joint. How wide is the post that goes into the strut? In metric would be nice. Thank you!

Brand new Lemforder 12088-01 measure 16mm

These are the late style for my 75.

Thank you!

Just to clarify, late style struts use a special wedge bolt.

Early struts use a pinch bolt.

Hope you aren’t just planning to run a standard hex bolt though a late strut instead of the proper wedge bolt.

FYI - the profile ground into the ball joint also changes to accommodate either the wedge (late) or a round pinch bolt (early)

Thanks @Superhawk996 for clarifying my post a little more. I should add wedge bolt style. I wonder if they are the same size anyway?

I would think the ball joint stem that slides up into the strut will be the same OD but I’m not 100% sure.

It sounds like Ninja got you the OD for the late (wedge) ball joint so should be OK. Just wanted to clarify post regarding which style was early vs late.

I assume you were trying to find non-OEM joint or maybe doing something unique for the track car suspension.

Oh, and remember the torque on that nut is only 14 lbs not 40 lbs. Damn Haynes manual!!
