FYI Warning!!!! 305 will not fit
You should not have any trouble with the 1/4 spacer. They only make the wheel stick out 1/4 inch more. That does not chantge anything suspension wise. all your angles are all factory settings. and we have plenty of threads on our studs, so I dont forsee any troubles.
The rear is up to you. In my opinion, I would say no. Every time you sandwich 2 things together, there is a great chance of them moving or slipping around. Now I know that a little play wont cause any issues. But with the truck being rear wheel drive, and all your torque going to those wheels, that is a lot of pressure on the lugs and spacer. although very small, it is just a better chance of something going wrong. And for 1/4 inch, I would not taken the chance... I doubt you even see the 1/4 onthe fronts.
