I addded the 45/90 hook by Yamaha which is made by sporttec in blue. I also added a black gel grip from ACO in the bike part department. Use hair spray to the inside of the grip, it helps to put it on. I just used a round 1/4" file in the hole and cleaned out the inside of the bar. I left the bar ribbed part on. The hook with the grip installs flush and the size is the same to the grip. Plus the blue of the hook is on the bottom and the grip is black, it looks great.
What kind of red ball ends do you have and do you want to sell one?
