I know you don't have a service hoist, but this image may help to show the re-inforced locations in general. Borrowed from the service manual. Your owner's manual shows the typical jack locations you are already familar with.
STANDARD PROCEDURE - HOISTING
Refer to Owner’s Manual provided with vehicle for proper emergency jacking procedures.
WARNING: THE HOISTING AND JACK LIFTING POINTS PROVIDED ARE FOR A COMPLETE VEHICLE. WHEN THE ENGINE OR REAR SUSPENSION IS REMOVED FROM A VEHICLE, THE CENTER OF GRAVITY IS ALTERED MAKING SOME HOISTING CONDITIONS UNSTABLE. PROPERLY SUPPORT OR SECURE VEHICLE TO HOISTING DEVICE WHEN THESE CONDITIONS EXIST.
CAUTION: Do not position hoisting device on any suspension component, including the front suspension crossmember, the rear leaf springs, and the rear axle. Do not hoist on the front and rear bumpers, the lower liftgate crossmember, the lower radiator crossmember, the down standing flanges on the sill or the front engine mount.
FOR PROPER HOIST PLACEMENT REFER TO (Fig. 5).
The hoisting points are identified by S.A.E. inverted triangle hoisting symbols (Fig. 5). The front hoisting points are at the bottom of the font rail below the hoisting symbol approximately 250 mm
behind the front suspension crossmember. When using outboard lift hoists, verify that the hoist lift pads have been properly adjusted to eliminate contact between the hoist arm and the down standing flange on the sill. The rear hoisting points are the leaf spring front mounting brackets. The hoist pad must be positioned to pick up the flanges on the bracket, not the leaf spring.
When servicing the leaf springs or the leaf spring mounting brackets, special provisions are required to support the rear of the vehicle. Position the rear hoist pads under the horizontal surface on the bottom of the sill, inboard adjacent to the flange and centered fore/aft between the jacking indicator tabs on the lower flange.
DO NOT HOIST ON THE FLANGE.
Place a soft pad between the hoist and the painted surface on the sill to avoid scratching the finish.
