Default OFAB or OFAC????

I have a 91 FRST!!!

My trouble is all the stickers have rubbed off the ecu! This now means i havent got a clue what ecu is in mine!!!

The dash is coming out at the weekend for wiring so im removing the ecu to find a manufacturers stamp!

If anyone can help by putting Ford part No.s for both ecu's i should be able to work out which is in mine.

I have rung my local Ford dealer and got some numbers to work on.
The 2 choices are:-
V90FB-12A650-AB
RV90FB-12A650-AB

Or if you know of a way of distinguishing between the 2 please let me know!!!

Thankyou all very much

After much research i have unfortunatly found that it is an OFAC ecu in mine.

Unfortunate because i have just bought a 195 Superchip for an OFAB! Ooops

If anyone knows of a chip for OFAC ECU's please let me know!

Thankyou all for your help i appreciate it!!!
