Thanks for the link.

I was specifically asking about block thermostats, Diverters are currently available from a number of sources including Baker's Auto ($110), Lincon Land ($115), Lincoln Parts International ($125) and Classique Cars ($148.50) + S&H.

What's up with the block thermostats? I see several posts saying they are not needed, other say they are? Also, has anyone found a source for these thermostats?

KULTULZ, I couldn't read the link you posted - it was in Asian.
