I just ordered the book about how to rebuild and modify your Nissan/Datsun engine at borders yesterday. I have looked through it before but I did not buy...what is funny is my mom wants to help me get my car fixed...she convinced my dad to pull the motor...he doesn't want to and thinks it is too big of a job...well I have removed, at one time or another, almost every bolt from my car in the last two and a half years.
This "extra" part is driving me crazy. I guess I'll figure it out when I have the engine on a stand.
