Penn 500 Conversion

[fishes]

I want to convert my Penn 500 to a 501. I was inspired this auction on eBay http://bit.ly/9mXFyb (hope the link still works). What I want to know is, where, locally, can I get the parts to do this? I figure the conversion will cost me more than buying a new/better reel but I want to do it for the learning experience as well as a little project to get familiar with these do-it-yourself types of reels.

Also, I recently got into the sport and bought a Sealine-X 50SHA and after reading some posts it seems that I should have gone with 40 and the lower gear ratio. As it turns out, my return period on the reel is up and I want to know if there are any concerns before I take this out, that way I can sell it and get the 40 everyone is raving about.

Probably should be two threads, I know.

If the above link doesn't work here are the specs -
