I'd just try the stock bushings. They don't need any maintenance. The Hotchkis bushings I have need to be greased, and the stupid Hotchkis grease seems to last about 4 weeks before you need to repack the bushings. Driving me nuts. I'm just going to put some more robust grease in there...I think Hotchkis is FOS and trying to make people buy their silicone grease.
So, try the stock bushings for less maintenance. If they work, then who cares about the urethane bushings...all they do is hold the bar and let it pivot.
