Help finding a part for buddy seat.

Hi all..... I need some help. I am missing a little rubber washer on a buddy seat 'Microssage' flowpath. Here is a picture of it. http://www.spapartsshop.com/16-5230WHT.aspx Anyone know where I could just order just the little rubber washer at the end of the pin? I have searched all over but this is the only thing I can find is the whole unit. I do hate to pay $20 bucks just for the rubber washer.
Any help would be greatly appreciated. Thanks in advance !!

I have no idea where to find the part you need, sorry. But, just wanted to say hi and welcome back to PF! Good to see you back around here for another season!

Thanks Watermom....great to hear from you. I have always been here..just haven't had any pool problems until now. Hope you are doing well!
