Welcome to the forum.
The exact interchange would be a '67 Pontiac or Buick A-body frame. Rear spring pockets were changed for '67, & any of the '67 Pontiac or Buick A-body donor frames are direct fit, though the relatively rarely seen 4door hardtop frame is slightly differnt.
'66 & '67 Olds A-body frames had different front frame horns due to the cross flow radiator usage.
Malibu/Chevelle frames are shorter in the rear section, won't work.
"64, '65, '66 Pontiac or Buick A-body frames can be used but the rear spring pockets are different. Have shipped, as well as have droped off many an early A-body frame. Best to you in yoor search to find a solid replacement.
