These are a couple of posts about replacing the original clock & oil guess what it is gauge. #201609 is a couple of months ago, although it seems longer. This shows how mine look & the old kit drops straight out, with the new settling in as if the instrument panel & the instruments were natural partners.
#198962 is from thirteen months ago & again it seems longer ago. Quite often I would do a job & run it for a while to ensure I'm not proliferating bollocks.
The mods to the sandwich plate didn't create a problem for me as I have the tools. PM me if you feel I can help further..
