I had similar questions in the 40-150 I recapped and rewired last summer. I think the micas in my radio were mostly type 6 and one or two type 4 (on the band switch) as listed on Chuck's site here:

It would be a good idea to check the production changes to see if the values were changed at any time. If not, I'd replace them with the value on the schematic.
