Well now I am going to rebuild my steering box since no FR boxes
Posted by: toms73novass ()

My main question is:

I have 2 64 boxes and my 63 box, from what I read, I believe the internals swap between them.

Obviously I need to use the 63 stub shaft to fit my column, but should I use the aluminum casing or one of the iron ones? Just curious why GM dropped the aluminum, I would assume some durability issues.

Be careful about wanting to swap pieces. There are 2 different length worm shafts and they are not interchangeable between boxes, the earlier one is shorter.
The cast iron box is stronger.

So you are saying I can not put the short shaft from the 63 (which has the worm on the inside) into the 64 cast box?

If you compare the 63 to the 64 Worm length the 63 will be shorter from bearing to bearing area. Didn't you say the 63 was an aluminum box? If I recall the aluminum boxes were 60-61 pieces.

You really need a 67-9 steering box to switch things out.

Take the boxes apart and compare the worm length, it will be very obvious if they are different.

Aluminum steering boxes were used 1960-63.

I've never heard or seen one that failed because it wasn't "strong" enough.

Most I've torn down have issues of corroded, rusted, pitted and worn internal gears (pitman shaft, worm & block).

Unfortunately, these parts are not available new.
