1958 Dodge
I look forward to seeing your progress on your 58. I have a 59 Coronet 2dr hardtop which originally had the one-year-only 326 poly (essentially, a .040 over 318 Plymouth poly) and Powerflite trans. Now has a 64 Chrysler 413 backed by a 62 Chrysler pushbutton Torqueflite. My 59 already had the 413 when I got it, but with a 68 Torqueflite and a floor shifter. I swapped in the 62 Chrysler (non-letter 300) trans so I could go back to pushbuttons while sticking to an aluminum Torqueflite, and also return to the drum type emergency brake setup on the back of the trans. Once I replaced the Powerflite pushbutton shifter assembly with Torqueflite, an early 60s Chrysler shift cable bolted to the pushbuttons one end, and the trans on the other. A NOS 59 Dodge emergency brake cable hooked to the 62 Chrysler tranny's drum-type emergency brake once I replaced the backing plate with one from a 56 Plymouth (62 Chrysler used a foot operated emergency brake pedal, 59 Dodge used a pull handle under the dash; cables are not the same).
Motor mount brackets are from a 59 Chrysler New Yorker. Rear axle is an 8 3/4 from an E body Barracuda, which fits well, but does need to be re-clocked. Found out later that a 65 C body 8 3/4 rear will bolt right in.
Not sure any of this is helpful to you if you're keeping the 325 Dodge motor, but the later stuff does essentially bolt in with the right selection of parts. Not like the 56 and earlier in which converting to the sixties or newer stuff requires that most everything be fabricated.
