(( posted from another thread, I forget who posted it but I copy'd it cause it's good info, you might wanna 2 ))
Just thought I would let everyone know all the parts I have found so far. I have been posting as much as possible to answer questions, getting tired of all the typing. Would appreciate it if everyone else would share the love and let us all in on any sites carrying P5 parts. Enjoy.
