I had brand new frt drums and turned rears on the '65 Rambler I had over the summer, but it still had a slight pulsation I couldn't figure out, but everything checked ok.. never figured it out, and sold the car in sept.. sorry I can't offer any other help, other than, maby the shoes are chattering on the drum causing a pulsation? I'v seen shoes glaze enough to do that... but new shoes or sanding the glaze on the old 1's is only going to band-aid the problem as it will come back... Speedway has a kit for '37-'48 Ford spindles that uses GM Metric stuff, but says it requires machining, so it would not be a direct fit setup like you want.. other than that, I don't know, but I'm sure there is somthing out there that will work.
