According to the shop manual, there are minor differences in the BODY MOUNTS for a closed car vs. a convertible. And of course, the Electra & Electra 225 are on longer wheelbases. I believe if you stick with a LeSabre or Invicta 123" WB frame from a non-convert / non-wagon, they should be the same. I have an Invicta 2-dr hardtop, it's fully boxed from the motor crossmember all the way back, and every pic I've seen of a B-59 frame 'looks' the same.
Hi , just reading your mention of FlightPitch transmissions . I have a ‘59 Electra 225 & was wondering how I can tell if I have one of these or a regular Dynaflow ?
Easiest way to tell is look underneath car. If you have a square trans pan, it's a flight pitch. If it's rectangular, it's a dual turbine dynaflow.
