I believe it is just a matter of wheel offset. The wheels on my truck now rub the inner fenders out back. I have them temporarily spaced out as it wasn't much needed. Once I get to ordering the new wheels offset will take care of problems like that. Keep in mind you probably will not be able to order off the shelf wheels if you want anything fairly wide. You will have to have them custom built.
Track width is center of tread to center of tread which again can be altered with offset. Pro-Street builds put the outside edge of the wheels front and back at the same width (majority speaking) yet track width on the rear is narrower than the front due to the width of the rear tires. If different offset was used with the wheels one might be able to achieve same track width even in those extreme cases of axle width differences.
I believe if using the original leaf type rear suspension or even a 4 link with the CV rear axle you would have plenty of room under the truck for wheels BUT almost all of the wheel would be behind the mounting point instead of half & half as with the original axle. The wider hub to hub will give you better handling as it moves the pressure point during cornering outward.
I am wanting to use the Mustang Bullitt wheels. From what I have read they have the same offset as the orginal crown vic wheels. I am not planning on using extra wide tires, or building a lot of HP. I am just wanting to build a cruiser, on a budget. I hope they will fit under my rear wheel wells. I acutally have a 78 that I will be doing this to in the spring. Right now just trying to compile all the info I can before I start buying parts. I would hate to buy part and they not fit., ect.

I have no knowledge of those wheels nor their relationship to the pickup utilizing the CV rear axle. I would look into being able to buy wheels that look the same but have the ability to alter the specs. I am finding many different styles, D and widths. Just looking at the pics I found I would say they look like the offset of my wheels. My front wheels do not hit.
They look like the wheels in the begining of this post. They kinda put me in mind of the old Krager mags from 30 or so years ago, but just a little more modern looking. I read if you go 05 or newer they have the most offset. But I am new to all of this offset talk. Custom wheels wont be in the budget. All I will be doing is the front end swap, rear axle, EFI 5.0, AOD, a little body and paint
The rear axle is out of an older crown vic ('02, it think). The bullitt wheels are from my '04 mustang. The '05 and up mustangs do have a different offset and sit deeper in then wheel wells. Right now the rear width is about a 1/2" narrower than the front. I also am operating under the assumption that if the front IFS & wheel width fits between the fenders, then hopefully the rear will too. I did some math based on the info that JGF100 posted for his suspension & wheels during the swap and think that my setup should clear just fine....we'll see.

I have the same intake with a Holly carb on it I am looking to get rid of. Won't fit the 460.
I did some measuring yesterday. 03 crown vic police with factroy tires on it (rear) Outside to outside was 75.5. My old 78 with 275 wide tires measured 77.25. The crown vic was actually 1.75 narrower than my old truck with the tires I have on it now. I do believe yall are right, I see no reason that it wont work
Jeff I think people are getting caught up in matching hub to hub width of the replacement rear axle and the original. If someone wants the original hub width and discs just buy a conversion kit for the brakes. A poor method of comparrison (IMHO) is track width as track width is a dimension you can alter. Your method seems to work quite well IMHO. With that you can add another 3/4" to the wheel on the face side from the mounting area out & however much you want that will fit to the backside.
Be sure to document your rear axle install so this issue can be put to rest. I am confident once you have pics of it under your truck with wheels on it they will sit back and say "What was I thinking?" The IRS under my truck is 9" wider hub to hub than the original 9" yet when matching wheels are put on it they sit deeper inside the wheel well than the fronts on the CV IFS. All this tells me is when I order wheels I can get the "deep dish" look I want for the truck on the rear. Matching the outside edge of the front and rear wheels I will get a little bit up front & the front and rear will look correct at that point.

I'm all squared up for the intake and carb already...got the intake for my birthday and bought a used carb locally. Thanks though!

The maroon & white truck is an all stock 2WD F100. I am 5'11" tall. The woman in black is my wife at 5'3". Our truck has a set of 1 1/2" drop springs up front. Before you go getting all gung ho on this project make sure you can get air ride for the front if that is absolutely what you want. It uses coil over shocks. If you want to see the build thread it is here:
