Vehicle build information tag

On my 64 the vehicle build information tag (near the VIN tag) has all of the paint worn off.
So All I have is a bunch of numbers..what do the mean?
Top row:  A100   90 (those are simple)
Sec Row:  3000   391 (axle gear?)   CHRY  RA36
Third Row  :  2200   3 SYN (3speed manual ?)  CHRY  A903
Forth Row          88   3600      940      1085
Fifth Row                 4600     91207213

So if anyone can tell me what these numbers and code mean, I will say thank you in advance.
My FSM does not give me this information.   Thanks to all

second row; (3000) weight, rear axle
(391) axle ratio
third row; (2200) weight front axle
(3syn) 3 speed syncro transmission
(a903) model of trans

the important ones..

Thanks, OK were there 3 different front axle weights in 1964 ? How did they differ ?

I only knew of two front axles, 2200 and 2500
the 2500 usually had 11" front brake shoes and some, not all had a different pin diameter for king pins.
the kits you get now might have nylon/nylock bushings in them, toss them back. ask for brass bushings. and when my set goes in I will ask the machinist to ream them to .002 - .003 clearance. they need some for grease otherwise in tight areas they snug up with heat.
