I hate to ask this, as I'm sure it has been covered way too many times already but heres my question:
1996 DX 4Dr MT 214k miles

I have the issue where the shifter/selector flops around and vibrates as I drive. Once I find where the gear is it's nice and smooth and tight but with all that slop in the lever, finding gears is a challenge.
Already put the ES kit in for the mounting bracket and the bushing at the engine bay side of the linkage. Where can I get a full rebuild/bushing kit for the bits at the base of the Shifter? I have had no luck finding one and they must exist. Advance/Autozone/Ebay/Amazon/RockAuto have nothing I can find

Thanks in advance for the help.
