No they didn't
The diamter of one of the pistons is different (can't remember which one it was, but I'm shure thet one is slightly smaller)
This information is proven or the RS... the Tuono... don't know.
On the other hand.... there are sealings available for the Nordie (Grimeca) front calipers.
You may ask at

This information is also available at the Yahoo group. Have a look at the 'Alternativteile-Liste'.
ciao joachim
PS if anybody is interested at 2 sets of sealings for a RS125 caliper.....
