I bought the mustang Steve bearing kit. I highly recommend it, and have on several forums.

The only thing I would say is,  based on our experience with our 66 coupe, is that the configuration that Steve shows in the pic is not ideal for the 66 with the borgeson box. We ended up putting the shaft retaining ring inside the column on the other side of the bearing, because with it on the outside like pictured it acts as a spacer between the bottom of the column and the rag joint. As a result the bottom of the shaft doesn't extend all the way out of the firewall and makes you unable to install a mount for the column at the firewall.

We're still assembling  so I'm inclined to think I might order another, but have him assemble it with bearing mounted up inside it's bushing instead of as pictured. 

Steve -if the bearing was mounted that way, would that configuration allow the shaft retainer be flush with the bottom of the column so the bottom of the column could be closer to the rag joint? I would seriously consider ordering another with that configuration.

Thanks,

Bob

I used Mustang Steves lower shaft bearing, worked OK for me. Not a lot of room to work above Borg box, but worked out well.

I designed the bearing retainer to be flexible so there is room for the shaft collar up inside the column as well.  Also, the bearing can be fitted from the inside of the column with the shaft collar below that to provide more room.  The OD of the bearing flange is 2-1/8" so it will just barely fit inside the column.  That way you can push the whole assembly up into the column as far as you wish, if the flange on the adapter is removed first.  That is good for a column that is not cut off square.  A set screw can be placed through the column tube into the extra length of the adapter sleeve to keep it from moving, also.

Although I preassemble them with the bearing pressed into the adapter, I can leave it out or configure it any way you wish - just ask.  Or, I can leave the bearing out and you can press it in as you wish.  If you already have one, the bearing is fairly easy to press out of the machined sleeve so you can reconfigure it.  Just DO NOT apply force to the center of the bearing when pressing it. 
Like a wheel bearing, the sleeve stretches to fit and may be loose after removal.  Some red loctite between the bearing and sleeve will make it stay put forever, but it doesn't hurt even if it is not a press fit.
If you guys come up with a better way that it could work, just let me know and perhaps I can redesign it or add another variation of the same product.
I now also offer the bearing kits with a 1" shaft diameter to fit other applications as well.
