My '40 Tudor frame was hacked about to fit a Cad V8 and Lasalle way back when, and has suffered some "adjustment" to the centre X-member and trans mount by means of a gas wrench. Is a '40 Mercury transmission mount piece the same (or close enough) to fit straight into the hole in my Ford chassis? For that matter, are the Ford and Merc transmissions the same for that year? And the rear mounting bracket? Thanks.
