signals

Hey I recently swapped my stock turn signals on my 1982 CX500 Custom with these: http://www.amazon.com/gp/product/B00CX7KXLE/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1 They are single filament, so they don't have the running lights on them. I got them wired up correctly, but my flasher relay...

I'm installing aftermarket turn signals on my 1982 Honda CX500 Custom. I am wondering if anybody knows how to remove the stock mounting brackets. Do you need to dissassemble/ remove the entire fork? I have attached a shitty picture. I will go take a better one for clarification. Thanks.
