Dont know if l can mention another site, but in the Avsim library the is the following file:

Tr727_gauge_update_1.zip
Matt Smith with original files from Stefan Liebe, Doug Dawson, Jimmy Foong(Sounds).

Although it was meant for fixed wing aircraft, it works brilliantly well in helicopters. Have it installed in Eh101, R22, Jetranger and a couple of others. There doesnt seem to be another one like it.
