Best place to part shop online?

[MrPlow]

Hello all I am new to the forums. I Am working on fixing up and old roketa bali mc-13-150. I was wondering is anyone could point me in the direction of where to purchase the parts. The manufacture website (http://www.roketa.com/product/produc...D=0&proID=2621) Has all the parts I need but i am not sure if it is my best option. I am mainly looking for an exhaust assembly and the wiring harness, and inboard cover. Any advice would be great. Thank you all and i look forward to being part of the community.
