From what I found out today, yes the rocker shafts are interchangable.
The rockers are different from 59-62

Seems my rocker assebly's have been rebuilt.
Rocker shafts hard chromed.
Rocker arms bushed.

This whould be why I was having issues finding parts.

I did however get it all squared away and was able to order the correct intake rocker for the # 1 cylinder.

Now just have to find someone who can bush it to my rocker shaft..... :-(
