Shop Manual For Reassembly?

You can get service / body/ chassis manual for 73 for free from MyMopar. A few of us here are why it is there.

The assembly manual? Probably need to search Dodge and Plymouth both. 72 and earlier is likely to have substantial differences in assembly. 74-5-6 if available would likely be closest.

For the record, here is what I think of the 67-69 version. Try not to think I am TOO negative, but the fact is, the Faxon watermarks are actually quite overbearing and annoying.

Also bear in mind that these manuals were once "unubtainium" were intended for factory internal use, and for a long time, I think only Gavin Grover or somebody had them. So at least they are somewhat available.
