GL is a 21 B 73
ZA is a 7 thinking 77 as it’s got the later selector inspection cover.
Thoughts?

The ZA has 2813496 lx., which means 3.05 2.19 1.51 1.00 , ratio , both boxes are 1-3.5 turns so expect the GL I put to be the same.

GL is M20 6cyl from that 1973 era. So cars like LJ and HQ.
ZA is probably that later 6cyl M20. ZB is M22 6cyl (WB), AB is WB 6cyl 3spd, ZE is V8 M21. ZD is V8 M20. Not sure what is ZC.
