ok, I went out and started checking and sorting.
the chrome fenders I could have sworn were 26" Huffy Middleweight are actually Wald 24" Middleweight.
here's the rear end of the deluxe rack. I think the 61 on Ratrod bikes has the reflectors if you look closely.
...and, after piling all of the parts for my main project (which to be fair, I haven't gotten to in 10 years) I have one complete bike and some left overs. I only have the one short chain guard. I'm thinking I should either hang onto the whole project, or sell it whole. that said, at least now you know what you're looking for. let me know if you need any measurements, and how you want me to measure.
