What do these numbers mean?

[Marteney, Steven J.]

I just noticed there something additional missing.  I believe the VIN should
start like:
1G2FW2...

FW2 is the Trans-Am, FS2 is all other Firebirds.

I have a 305 TPI from a 1986 TransAm. The then engine number is:  2GN207358,
but
I never saw the car the engine was from so I had no VIN.  I called Pontiac,
and
they could not cross the engine number to a VIN.  However, the engineer gave
me
some numbers to make a complete VIN:

1G2FW87F    2GN207358

1 = U.S.
G = GM
2 = Pontiac
FW = TransAm
87 = hard top (not convertible)
F = fuel injection

2 = I was told this is a, "check digit"... "is not important"
G = 1986
N = Norwood (assembly plant)
207358 is the numerical sequence.

I want to purchase a whole rebuilt computer.  My local parts stores are
looking
for an F, G, or H code.  Some people tell me the 8th digit of the VIN is
what
they want.  In the case above that would be F.  However....  If  F = fuel
injection, why would NAPA say it could be F, G, or H?

I have not been asked if it is automatic transmission, or manual, or
anything
else.  Why, are the automatic and manual computers the same?

TIA
