Z1AExhausts
Posted: Mon May 26, 2014 7:44 pm
Hi, I have somehow posted the question on the New Here board. To cut it short, I have a 73 Z1A. Build date 11/73. What is the correct exhaust numbering for it. I have the numbers KH1900Z1/750Z2DGM13236S on my exhausts. I have seen an Ausie forum which states that the numbers for the A are smaller at early production, and larger at later production. Can someone tell me what he difference in the sizing of the stampings is. Thanks
