Hi again Joe, thanks for helping out.
No its not the riveted on collar. Il try and attach a couple of photos.
Here goes.
photobucket photobucket I wonder if the other trucks have a slightly different box - in the link you gave pics 13 and 14, i wonder if some use a bearing retainer (the part ive got in the rebuild kit) which retains the lower worm bearing, but maybe i dont need it as as the worm bearing adjuster on mine seats against the lower worm bearing?
