What finish should the accelerator rod be on a SJ 10-64 289 car be? Should it be zinc or zinc dichromate? Reason I ask is I am thinking of taking my parking light retainers to be replated and they do a batch for $75 and I'd like to include as much stuff in there to be done. My door strickers, license plate light, and hood pin are ok. Are there any other pieces that need to be done in this finish?
Thanks,
Chris
