I tapped the DOM for 7/8 18 tpi left and right hand TRES.

I used a 5/8 12 point socket in a T handle for one tap.

 

I had to weld a wrench to a piece of tube for a handle. I can not find a tap handle big enough for 7/8ths taps. This is a 9/16 wrench.

Reaming the pass side TRE for the drag link.

OEM 2000 Nissan Pitman. 91 up D21/WD21/D22/WD22 are all about the same size. They all should interchange 91-2004.

 

We reamed the pitman from the top to keep the drag link parallel to track bar.

Testing the new bigger TRE

The HUGE TRE just clears the frame. 2000 Xterra pictured.

Testing for clearance during flex

All painted.

Option 2.

Cut DOM to length.

92 WD21 Pitman puller is super tight.

93 D21 Pitman puller is looser. Minor grinding to puller to fit.

94 WD21 Pitman has plenty of room for puller.

Example of reamed and unreamed. These are the smaller 91-92 version. 93-2004 are much thicker but same overall size. The taper is different for the TRE. But that is enlarged anyway with SAS.
