Well this gives me a good excuse to change the fluid/filter and install the new chrome pan i got from summitracing a year or so ago.
I would not put one of the diy drains in again. Just get a pan that already has the correct drain bolt in it as it sits flush with the bottom of the pan. The chrome pan with drain costs about $30 right now.http://www.summitracing.com/parts/SUM-G3887/?rtype=10
