Going to install some Rusty's diff guards... They cover the bottom half of the diff and use the bottom 5 bolts. Will I he able to just pull those bolts and install the guard without breaking the seal and losing my fluid?

I have been running a few searches and think I will be fine. But If I go with a 15x8 wheel w/ 4 bs, will I rub with a 235/75/15 tire at stock hieght? I already run that size tire on 15x7s and don't have a problem, But i'm not sure if the new diameter or bs will effect anything. any advice is appreciated.

Edited for reminder of the rules here.
Catalytic Converter Laws
Rules for Replacing Converters
In 1986, the U.S. Environmental Protection Agency issued new guidelines for the construction, efficiency and installation of aftermarket catalytic converters. All CleanAir converters listed in this catalog have been designed, tested and manufactured to meet this policy.
In addition, CleanAir converter listed in this catalog is appropriate for use under the current requirements of the California Air Resources Board (C.A.R.B.).
E.P.A. guidelines state that replacement converters may be installed only in the following situations:
1. The vehicle is missing a converter
2. A state or local inspection program has determined that the existing converter needs replacement
3. Vehicles manufactured prior to 1996 must have more than 50,000 miles, and a legitimate need for replacement must be established and documented
4. In cases of OBD Il-equipped vehicles (1996 and later), the O.E. manufacturer's 8-year/80,000-mile warranty must have expired and a legitimate need for replacement must be established and documented.
Please note that Federal law prohibits removal or replacement of a properly functioning O.E. converter.
When replacement of the converter is appropriate (as outlined above), the E.P.A. further requires that:
1. It be installed in the same location as the original
2. It be the same type as the original (i.e., two-way, three-way, three-way plus air/three-way plus oxidation)
3. It be the proper model for the vehicle application as determined and specified by the manufacturer
4. It be properly connected to any existing air injection components on the vehicle
5. It be installed with any other required converter for a particular application
6. It be accompanied by a warranty information card to be completed by the installer.

5mm extra rubber hanging over the side ain't going to matter, and 7.5mm added to the tire's radius won't much either.Even though you upgraded to wider wheels, the backspacing is measured as the distance from the inner surface of the mounting area to the inner flange. 4" BS is the same even on say 15x10 lol.

In all reality, the cat gets rid of one pullutant but because of it's reaction to other parts of the fuel it actually creates some others. But what I did was get a high flow cat from Summit, "MagnaFlow" and had it welded on. You get the performance and you keep the emission ****'s off your back. $69 for cat, $50 to intall.
