I have what is registered as a 1975 Austin Mini. The original VIN and engine identification plate are gone. I was told when i purchased it, it had a 998 in it. But after looking at it and doing some research, it seems to have a 1275. I believe that it is a 1275A and not an A+. The casting stamp on the head is 12G940 and the distributor is a 41257(25D). From what i can tell this engine is out of a Mini 1275GT, but I am not 100% sure. Is there anything else that I can look at to further identify my engine.
