I gotta knocking noise coming from under the car, think its a cracked flexplate so Im using it as an excuse to install my ss3600 this weekend. Which flexplate should I order?

Internal or external balance?

After browsing the web some people are having problems with the TCI units, what other brands you guys using?

EDIT: nevermind, that thread was from 2005 and TCI has since fixed the problem.
