On the isolators, in many cases, the rear pairs can be the same. Uppers and lowers, with ONE of the pair having the "insert" where the bolt goes through and indexes with the matching lower insulator. Fronts (core support insulators) are usually different, but still in matching pairs. Those center sleeves are there for two reasons. To ensure the two mount sections index correctly when installed AND to limit the amount of compression from bolt torque. So the mounts don't sqush more than a specified amount at recommended bolt torque.
Wondering if your front frame has a mix of "Torsion Quiet" and 1969 insulators installed? Just curious.
To effectively read an older Chrysler parts book, you have to understand the terminology the engineers used (which CAN be different than what Ford or GM would have used for a similar item). ONCE you can "get into their head", so to speak, it can all become easier to deal with, by observation. Chrysler called their warehouse parts reps "Order Specifiers", the people the dealership parts people would call for clarification or help in finding some things. GM called them "Order Interpreters", for example.
Basically, illustrations first, to get to the parts section designation. Then to the part number grid pages to find that section, then go laterally to look for the quantity (per car) number in the column for each of the body designations (listed at the top of the grid). Once you figure this out, they are really quite easy to read, by observation. Easier than similar GM books, where you had to know the correct terminology for BOTH parts, option names, AND car models! Similarly, once you get these things figured out, there's LOTS of stuff hiding in those books!
In many cases, the Chrysler part number might be cast into the side of the insulators. The exposed outer circumference. Plus possible color codes for the assembly line operatives to put the correct item in the correct place.
(The other thing is, What are you doing with a book that big and heavy IN BED?)
