motor clamp and cooling fan

ok so i've decided on this motor for my 1/8 buggy conversion http://hobbycity.com/hobbyking/store...idProduct=6678 and it has a pressed endbell. im going to be doing some pretty serious bashing, and would like a motor clamp for it. where can i get one that fits? also, is there a heatsink/fan available that will fit this motor? brushless noob here, any advice is appreciated
