4" to 4.5" front wheel conversion. How??

I have a 72 Demon that I want to convert the front wheels from 4.0" to 4.5". What all do I have to change and what would be a good donor car to get the parts from? Does anyone make a conversion kit that is reasonably priced? Thanks, Andy

you need a 73 and up donor. Great time to upgrade to the disk setup.
You'll need the upper control arms, the spindles and the associated brake hardware( rotors, calipers etc.)
I'll post more later.

I would agree with Mopower71, convert it to discs. There are several articles posted on the web. But here is a link to bigblockdart

I actually have 72 Charger spindles and brakes on the front of the Dart. I haven't finished the plumbing and put the car away for a while. But the spindle size is right. Different year B-bodies are different I beleive. Also there was an article in a mopar mag recently about this, It was written by Bill Reily.

Thanks for the info guys.
