What kind of bushings should I get for my front and rear swaybar endlinks? Is Poly a good idea for these parts? Is there a certain higher durometer rubber bushing from gm? Should i just get stock replacements?

I'm currently using the stock swaybars and it may be a year or 2 before i upgrade the bars to a 35mm hollow. Theses bushings look tottaly worn out right now.
