I had bought this set a while back and I eventually managed to replace them the other day, but... It didn't work! The length of the bar is too short to reach the end of the new grips, i don't know where to buy a metal bar, and even if I do, it'll cost a lot to get them and have them cut in two small pieces as attachments to these grips. I noticed this thread reel is tight enough if I squeeze into the vertical attachment from one side and the main bar from the other, but I'm not sure if it's strong enough. Is there any other way I can get around with this?
