I believe 03049872 was the part number of the final "Refitting Kit".
03049871 was the "Hydraulic Tappets Refitting Kit Tools"
I've got PDF of the parts list and procedure if you need it.
Can you share the PDF? I have a couple of images of the tappet and tool with dimensions. They tappet dimensions do no match what I pulled from my engine. Mine are longer.
See my post regarding checking the recall work after installation. I found the rocker arm pad and the valve stem were both damaged and 3 of the 4 tappets stuck fully extended.
Also appears that there is low oil flow thru the rocker arms and onto the valve stem.
