Just read this whole thread.. My 67 Z had an NOS MO302 and I thought that was cool.. but a real ‘factory’ DZ 302 67 Z-28 ! Love it !
Sweet car !! ����

Tommie, check out my post earlier in this thread. It explains how the DZ was swapped in.

With only 41k miles on the car, upon closer examination then disassembly, the lower steering column bearing was shot. After some research, it appears the bearing is no longer available but several places sell a retrofitted end piece with new bearing for around $80-$100. So I started looking for a bearing that’s close and found it on Amazon. The OD of the bearing was just a little too big so I used my brake cylinder hone and after about 45 minutes of working the plastic end piece, it fit perfectly.

Here is What I used:

The Bearing is encapsulated into the Lower Bearing Housing, I never thought about extracting the Bearing ONLY and re encapsulating it into the housing - If that is even possible. Credit Darrels preservation for turning me onto this option.

I just finished Restoration of my 1968 Z Column

That's exactly what I did. I incorrectly called the lower bearing housing "plastic end piece". I pressed the old bearing out of the lower bearing housing, using a brake cylinder hone I opened it up for the larger OD of the new bearing then pressed the new bearing in. Based on pics of your new bearing housing, it looks identical to mine so thinking Darrels, SS396 and HB City all doing the same as I did only they are likely more efficient at opening up the lower bearing housing to accept the new bearing than I am using the hone. Here's the completed column. I saved the original paint on the interior side of the column. buffed it with some 15 year old Einszett and it came out nice.

I used the original grille and headlamp trim. They aren't perfect but are still pretty nice so couldn't bring myself to replace them. When I tested the original headlamps, I kept my fingers crossed and for a second I thought they were good, they were not. High beams work, low beams appear to have burnt-out when I powered them up. Bought replacement T3s at Lectric Limited and they work great.

Had a few minutes to mess around with Youtube today. Here's the last and best dyno pull from last year:
