Serial numbers and build timing
Fifth gear plates sit inside the transmission, and gearboxes from different build periods can contain different internal parts. Serial number checks help confirm that the plates you buy match the case you are working on. Fifth gear work often uncovers wear on the sleeve and hub too, so inspect those parts along with the plates. Look for rounded edges on the key contact surface and uneven wear on the gear cone, both of which suggest the synchro should be rebuilt.
A transmission shop can often check the serial number and gear wear during a single teardown, which makes better use of the labor. When reassembling, keep the plates oriented as they came out and fill the gearbox with the fluid the vehicle requires. Test each gear in neutral with the engine off first, then on a short drive, and recheck the fluid level once the vehicle is warm.
