Possibly later style swing arm? going with the the stock caliper 1 year only wheel combo?
i think you mean pre 75, common drum brake variant, yours being the earlier (no cush) wheel deal, but with the latest, considered stronger swingarm upgrade
an experienced owner with your swingarm said it was fine & especially if the bushings check out ok (no play), might as well go as is but with the kegler clamps
the swingarm mounts up to a cradle via pin & bush that had upgrades

check for play, then go from there
the cradle then bolts up to frame via (rear) iso mounts, the cradle also bolts up to back of the engine
