I used wrenchhead too. HTe order came a week late and looked like it had been through a thresher. The customer service was horrendous. I now use www.kragen.com.
I haven't ordered online but, you can search your local stores inventory and they have an excellent range of parts. They even had tranny filters for my 72 mercedes.
