Manual steering boxes were same for several years ( Camaro , Chevelle , Nova and full size cars same just different pitman arms ) , longer pitman arm and different steering knuckles made for quicker steering ratio for Z cars and other cars ordered with f41 suspension . Have read if you ordered optional f41 on top of Z28 (very rare )steering boxes were couple turns less lock to lock ( different internals same outer casting and casting # ) and very difficult to turn if not rolling ( no fun at all to parallel park , not even for Popeye ) . Yours looks to be cast on 105 th day . The assembly date was typically 5 + - days after . Assembly date should be stamped on raised pad ( just need to wipe off dirt to see stamp ) near cover . Julian date followed by 9 for year . Hope to see this one at WTWW in Fairborn 2022 !
