Hi Steve,
I've just done mine so it's fairly fresh in my head. If you measure
your shims assuming you are OK with a micrometer and you are lucky you
will have some shims thinner than the others? It is a bit laborious
but if at least one of your shims is thin enough to give you a
clearance on all the valves then you can easily calculate the correct
sizes by using the thin shim as a measuring shim in all of them.
Failing that you need to beg or borrow some thinner shims to enable
you to get measurable clearances. if your thinnest shim is perhaps
95thou I would go down to about 80-85 and you will almost certainly
have measurable clearances I managed to borrow 4 thin ones to get my
measurements.
I think I read somewhere that it is not advised to use shims less than
80thou (my thinnest is 79).
Sue Miller has a large selection of shims and I'm sure she would post
some to you if you cannot get them locally. I know they are the same
as Hillman Imp and I have been told they are also Rover SD1 but the
Rover shims do not tend to be thin enough.
Another thought .....If you know someone locally with a surface
grinder you could get acouple of shims machined to use as measuring
shims.
Sorry this is a bit wordy I hope it makes sense
