Glad to be of help buddies, and thanks for the encouragement. I will post another nice and easy tip in a new thread, very much worth knowing.
Matt nice one
Jaybee Very true and that is why I am still looking around. Worst case scenario, will use regular ones till I find correct rivets, as you cannot see them unless you look for them. I have an extra set, so will do it when found and switch over.
kapteenikosmos Yes they are on the dim side, you can still read most of the details on the instruments but with difficulty. I suggest you do it now and get this out of your way.
By the way, an overnight soak in white vinegar is perfect for almost any amount of rust, in case you do not like dealing with acid.
Acid probably gives a quicker result, but depends on the strength.
See attached photos of my Mustang's heater blower. I could have left it more that 6 hours and it would have gone even whiter. After the soak, a good wash and it was ready for paint, barely a need for any scraping, last photo.
