Yes, all the '58s had Bendix Electrojector EFI, the firsst electronic
system ever, it was actually developed for use in airplane piston
engines and adapted to automotive use.  There were a few more
300Ds made with EFI than Desotos, and a few  Dodge & Plyms
too. The  Desoto had the EFI on the 345 hemi and EFI was with the
392 hemi on the Chryslers.  Tom White's gold DeSoto Adventurer
'vert is the only known survivor, at least in Desotos, there might be
some 300s with it still maybe - he found the EFI unit in Harrisburg PA
from the son of the Chrysler factory service rep who took it off a car
when it was converted back to carbs, and paid 5 figures for it... the
system actually worked very well, but the fragile wax and paper
capacitors in use back then just didn't last... Tom being an electrical
engineer rebuilt the analog unit using modern polypropylene caps and
with a few other tweaks it works fabulously today... there was a big
thread on this car on FL.net recently - in my opinion Tom's car is
probably the most valuable stock standard production postwar Mopar in
existence... wish I could find a Bendix EFI for my '58 FireSweep, but
it wouldn't be exactly authentic with the 350 B wedge engine. The Dodge
and Plys did have the EFI with the 350 B block however, iirc.

Correction - the DeSoto EFI was on the 361 wedge - the 345 hemi being
dropped after '57. The only EFI on a hemi was on the 300-D.  My
300-C  had the 392 hemi with the dual 4 bbl's, and the EFI really
did deliver a significant power increase - I can only imagine how
awesome the EFI 392 must have been... be nice if the couple remaining
EFI 300-Ds would actually be finished and driven, now that Tom
White  knows how to make them work...

See now the New Yorker in 62 Didn't have a Bendix system.  It was a Bosch.  The injector pump was under the distributor.  That was not electric or electronic.  It was a manual similiar to the old diesel injection.  I guess that was the first attempt to try to get around that.  Apparently Bosch was making those systems for Mercedes back then.  I can tell you the plumbing coming from that dustributor setup was a nightmare.  Someone took allot of time to bend all the tubing.  The Dist cap was way up over the alternator.  But it looked like you set the ignition timing independant of the injector timing. 
 
I forget the exact number, but Chrysler Museum told me there were 3 or 4 built with only 2 hitting the streets.  I got the pleasure of discovering one.  That was a 413 with A/C in a 62 New Yorker 2 Door.  Chrysler Museum bought the car and I had heard it was displayed for a time.  I've never been to the museum.  The location of the remaining are unknown
