Chuck,
Too bad about the experiment, CRC makes pretty good stuff. Please proceed with silicone implants
and lets us know how they feel. [Ahem}
I've ordered the Wilwood shim kit as Ron described but it's backordered 10 days.
I'm going to bleed the system and install the shims then. The streets are still a mess here so not sure when I can try them but will report ASAP.
Good luck and please report any results.
