Still trying to find out information on my F4.
When I picked it up 15 years ago it there was nothing on the back. It may have had a water tank but i dont know for sure.

The #on the firewall looks like:
2RHI0IC083

Is it 2RH101C083?

I know the 2 = Vermillion
RH=Richmond,CA

any help on the rest? I looked back at the old threads but they dont match up with codes.

 

is this the same # that's on the glove box door?

 

Looks like the number is from the firewall. This is the number that can decode the date of manufacture and other misc things. Have no idea how to decode it. One thing I know, RH is Richmond, CA.

 

Firewall tag = Buck Tag.

Almost impossible to decode as there's no parts catalog info on them.

Richmond CA Assembly Plant: RH thru 1952 / R = 1953/55.

The San Jose CA Assembly Plant replaced Richmond in 1956.

1956 and later: R = San Jose
