Now there you go, typical Billy Durant and nothing standard or the same. The AEA card is for 1930 - 31 407 Oakland with Serial Numbers C-1010 and up.
Cards for 1931 611, 614, and 31 / 32 618 Canadian with 22A and 22A Improved are IG-4203 as is the card for the E 618 / E 670 Frontenac. For some reason the 32 685 Fronty is IG-4303 which was used on the 32 680 De Vaux plus the IG-4309. Makes some sense with 680 De Vaux, 685 Fronty and 633 Durant mostly the same body / fenders / dash. We just altered a few parts Canadianizing them.
Chilton Interchange which I just learned is all Shurhit part numbers shows 1930 614 as IE-27, 617 can be IE-29 or IE-27, 1930 - 31 612, 614 as IE-27, 1931 610 as IE-27, 1931 619 as IE-27. For some reason no mention of the 407 but 610 the continuation of the 407 with 4 cyl W8. Had the 621 / 622 been built they were to have the E!-27 also. Chilton being US doesn't have Canadian info. Easy to convert the EI-27 as IG-4302 since we know that.
And the games go on with Billy's empire of no two cars the same plant to plant Easier to put a coil under the dash on the firewall and use a simple on off key ignition switch on the dash ha ha
