Aaron, I used a piece of stainless steel rod, it was from a wall shelf , I put a big loop at one end, big enough to get the clutch and speedo cable in, the other end a small loop to go around one of the studs of the out put shafts side plate, it needs to be around 8" to 10 " long.
I bent the rod to hold the cables about 2" off the headers, it works great. For something easy to find, use a welding rod not to small in dia. so it's stiff enough, but small enough to go around the side plate's 8mm stud, break the flux off with a hammer.
Figure the rest out for yourself
