69 SS Weights:Malibu vs. 300 Sedan vs. 300 Hardtop

[mockingbird812]

I am interested in official or anecdotal "apples to apples" weight comparison among these three models. Particularly interested in L78 4 speed , but a like comparison of similar drivetrain (i.e. all with L35s and TH400s) is fine too. Ideally, I want to learn what the differences in weights and total weight for each of these models.

Whatever info you have, please note significant (weight-wise) options, i.e. engine, transmission, bench vs. bucket seats, etc..

Thanks!
