I'd have to check, but I think I have M37 in the shed and it has no cooler line fittings

>We're on the same page Andrew. The starter ring gear was made onto some of the BW torque converters, I know it was for the 63 195.6 in an American (M35). The GEN-1 V-8s were both ways (on TC or on flex plate) depending on year -- the early ones I believe were on the TC. I'm almost positive the M37 has external cooling line fittings, but the M35 doesn't. I had a 63 and a 65 or 66 case, neither had cooling lines available. I'd bet if you ordered external cooling you got a M37. That would make sense, as you'd really only need external coling for towing apps, which would need the bigger engine (232 vs. 199) and tougher trans (M37 vs. M35). Just speculation at this point though.
