Is this swap supposed to be a simple plug n play? Because I am in the midst of doing the swap and found that tje Me steering coupler/guibo does not fit on the Z3 rack. The coupler is too small. Its a brand new coupler. Both the new and the old coupler fit on the old M3 rack, but neither will fit the Z3 rack.

Do I need a Z3 coupler? Was the wrong rack shipped? What?

TIA.

You must have wrong rack. My fit just fine.

will fit just fine...

Thanks guys. Splines on the input shaft were bad. A new "new" rack is on the way.
