handle bar controls 77 1000 project...

ok guys i plan to run aluminum bars on my 1000 but i can not fit the wires through the bars i could modify my stock controls but they are in good shape and i would hate to do that. is there a set from another bike that work well or is there an after market set available?
thanks

thanks for posting those, they are pretty nice looking. i was thinking that i will just drill some holes in the bars so that the wires have some where to hang out of and that way i dont have to modify the oem control housing. then i will just wrap the wires with some russell wire wrap and finish up nice and tidy.
