Weighted selector rod. UUC sent me an extra one by mistake. e36 5spd (328, M3, 323, late model 325) fitment (may fit others - 198mm lenght). From UUCs website it also fits the e34 M5 (5spd).
It is brand new and never installed:
List: $129 USD + shipping, taxes and duties.
First with $100 at my door gets it.
