No, because they already have a jig and are doing it as a business. If you took it to a random welder to set up a custom, one off application it would. That business is banking on defraying the cost of the jig and the set up time over dozens of units.
Plus, they're using a mustang rack for steering, which is probably part of why it's narrowed that amount.
And why is Dodge Dakota suspension better? There's probably less aftermarket support for a good handling Dakota than there is for an A body. And having owned a Dakota, it's not like they handle spectacular to begin with.
