I've read that LA-built cars' unibodies had black undersides as opposed to other plants using a grey color; maybe someone can confirm or correct this. Cars intended for CA sale generally had different advance timing curves, distributors & carbs, air cleaners were often the snorkel ("silenced") type, chrome tailpipe tips were omitted (except some Hemi Bs), and in some years had closed-loop fuel tank venting. Cars intended for high altitudes (Denver for example) also differed in some tune-up specifications.
The Calif Air Resources Board (ironically, "CARB") started dictating changes with the '66 model year, and noise levels were legislated starting in '68.
No doubt there were exceptions: I've owned both silenced & unsilenced air-cleaner '68s & '69s, and I can recall seeing a couple brand-new Bs with chrome tips during that time. Some laws took effect Jan 1st, others were model-year.

Well the California cars have different emissions systems. They have a return vent line. A total of 3 lines. The 1970 only made 1 year California Challengers (I believe) did not have the cool rear valances where there were cut out for the dual looking exhaust tips. Not positive about this but seems like I read it somewhere. I believe they had the turn down style due to Ca. regulations. The California Challenger 70 model cars also had some kind of differnt part on the driver side rear that was bolted on the frame near the resonator. Its metal and bends over approx 6 inch by 6 inches. In told its a hard to find part. Dont know if its a one year only kinda thing though. California cars have an E designation in the 5th character of the vin. These are things I have read, and I believe its true. I am sure there are other differences. I was thinking there was another difference. The crankcase ventilation was different, which was the reason for the extra vent line. As others have said, in Ca.cars the buildsheets are not as prevalant. My personal experience is that California cars are not prone to be as much a rust buckets as Hamtrack cars can be. This primarily due to that many cars went to Nevada, Arizona, and other dry western states. I would like to hear from others about differences too. Edit* when I stripped my undercarriage it was black primer on the bottom also.

How about the actual construction of them? Sheet metal, floors, frame rails etc.........

See if the pics work.
OMG!!!, MrNormTA...I couldn't figure out where that piece went for the life of me. Thank you sooo much for posting the picture!!! 
Mine is black under the undercoating too, had the turned down tips for the rear exhaust, and a 2 & a 1/2 inch sealed pipe instead of the fuel-line type vapor separator in the trunk.
1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's
1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

Just to clear it up some more.... LA did build cars for other states without N95. Hamtramck also built cars with N95 for California sale. LA seems to have halted all E-Body production in or around mid May of 1970. This explains why some WSS Challengers were made at Hamtramck in June & July. Initially they were all slated for LA build. If anyone has a LA built E-Body (especially from May, 1970) please register, I would love to hear from you; http://www.hamtramck-historical.com/register.shtml

Actually I was wrong about the approx 6in by 6in plate being on the drivers side. It is on the passenger side bolted just behind the rear fenerwheel. It protects the fuel lines I believe. They repop this now. The piece of metal has a bend almost 90 degrees the last one inch and two very small screws hold this to the bottom passenger side fenderwheel at the very bottom lip.
