Thankfully I replaced the converters at a friends shop that has a lift,and welding equipment.It took quite alot of heating up and bending to get it right.Cant really complain,as it ultimately turned out successful,but for anyone thats considering replacing both cats on a 4.2,be prepared......its a backbreaking bugger

Now ive got to figure out how to get to the two upstream 02 sensors....
I also did a little research and have found out that they intend to extend their air standards to OBD compliant vehicles up to OBD-II standards. So if you have a car that is from 1995 or older and your catalytic converter goes out, you will soon have to comply to OBD-II cat standards. It's total BS. I'd love to join a class action to sue the pants of off CARB for these measures, but the money involved to make it happen makes it completely prohibitive. They nail California citizens with this kind of stuff incrementally and creep it behind the scenes so not only do you not know about it, but they do it slowly so you don't even care by the time you need to fix something.
However, what I am really curious about and I was having a discussion with a friend here at work about it is, are the catalytic converters in the other 49 states actually different than california OBD-II catalytic converters? I'm an engineer and I was thinking like one. My truck was build in Oklahoma and we were finding it hard to believe that Ford would have set up two different component lines for each catalytic converters; one for California only and the other ones for the rest of the 49. So our thought was that they are actually all the same, except they don't have the certifications like you mentioned. So we were wondering if you could by a modern catalytic converter from somewhere outside of california and replace it and see if it passes smog. Can you verify this? I'm really curious to know.
On a positive note. I deduced that it wasn't my pre-cat but the cat right behind it and I took it to a shop that verified it for me and they are going to replace both cats for $500 using universal aftermarkets out the door. So I can technically buy two of them for the price of 1 ford cat. I have smog certification coming up in a couple of weeks, so it was timely I guess. But the whole thing has just been very frustrating. Either way, I got off fairly light. In the wallet that is.

Now to your next question. Are California converters different from normal converters? That depends. In simplified terms, they are, but how they are different depends on the automaker, the model, engine, and year. It also varies witht he type of fuel the vehicle uses. Some automakers make it easy. For example, an Focus has only one option for each engine, and they just make all the Focus models to California specs. There is no Federal version. On the trucks however, there is such a discrepancy between FED and CA regulations, that Ford figures they can save money by making them different. Ford is actually the worst of the big three for variation of parts. For example, between '97 to '02, Ford had two different cats for FED and CA on the 5.4L, and different cats on 2WD and 4WD, and different cats for some cab options, plus different cats on regular and Flex Fuel. All in all, that is half a dozen different cats on the 5.4L F-150 alone. Most these parts are shared with the Expedition as well. But the 4.2L and 4.6L use different parts as well. I have to admit that while I dislike GM with a passion, they did one thing right. They use the same converters on all '99 - '05 C&K 1500 trucks with the 4.3L, 4.8L, 5.0L, and 5.3L engines, and also some 6.0L regardless of cab configuration, emissions compliance, or drivetrain configuration. Its also something they did wrong, because said cat assembly is a piece of junk and fails all the time. But the interchangeability was a great idea.
