I know this is elementary but...! Just disassembling the rear drums on my donor and they bear no resemblance to those in the Haynes manual. Ive had to remove the hub nuts then use a puller to remove the drum. The drum and drive flange appear to be combined (inseparable). Is this normal - never seen it referred to before?

probly rusted together,no screws just give it a whack with yr hammer
