akapjay 41 Report post Posted May 22, 2022 (edited) Wasn't sure where to post this, but am looking to ID a manual ZF box. Identifiable numbers on the box: 1053401107 02222612218999 12219369012225 Based on the old Google I think it's originally from an E36 325tds, ie: a S5D 260Z but hoping someone has more knowledge here that can confirm. --- Next Q, if it is indeed a 260Z, how could I go about confirming which variation based on the physical box, or would I need the original VIN for clarification? IE: S5D 260Z - THML S5D 260Z - THMY --- Furthermore, if anyone has gear ratio knowledge - this is what I've managed to dig up online, just looking for confirmation these ratios are correct?
