Mine has to be welded on, but you get the benefit of having a bearing that has a hardened inner race, unlike the ones that have exposed rollers that rely on the mild steel pedal shaft as the inner race.  I have only seen a very few shafts that would even work, usually on garage kept, low-mileage cars.

If your shaft is PERFECT, then it will work for a good while with the roller bearing kit.  If it is perfect or completely shot, it will work fine forever with the MS sealed bearing kit. 

If your pedal support is worn so bad that the holes in the sides are elongated, the weld-on will make it like new.  The clamp-in type typically are not a good fix for those problems.

I bought Steve's complete pedal support assembly with the bearings already set up. It's a nice upgrade over the factory support, much more substantial. I think it's a pretty good deal for you get.

i had already installed the Baer track disc brake kit on the front and used a bendix brake booster and new power brake pedal.  I have also now got ahold of the rear baer track kit so I will have 4 wheel disc.

I will probably need to look for a different master cylinder.  I used one from i believe the early maverick. Will have to double check what it was from but it was new not rebuilt.

I also have the Wilwood como valve that is adjustable proportioning valve and distribution block combined.

I am switching to manual transmission now so I am actually adding a pedal to my current non-manual pedal support so both the pedal shaft and pedal support are never used. just figured it might make a smoother operation with the bearing support and not have to worry about it wearing out.

 

Go to my website and take a look at the pedal bearing page.. There are pics.  I can email you the instructions if you email me so I can reply.  steve@mustangsteve.com

Installation instructions are now online with pictures.
