Those don't fit all those models. I have a set of billet bushings for a 510 and they are totally different. those most recently referenced are visually like the ones for the 280zx.

what's wrong with those? nothing. doesn't come with the one for the bottom of the shifter and the delron is a better material.

i just like to keep an eye out for ways for us to get some cool parts too. and i probably need a set for my shifter, might as well, everything else's been replaced.
