Ok I have a few questions.

First off the original 6 is installed.
I want to go with power disk set up. Is there any issues with wheel spacing? If I use the kit that allows to use the stock (drum spindels)I'm sure that it will push the wheels out to far.

Next if I use drops is there a safe limit that I can use before other steering issues are encountered.

Power steering, if I purchase a power kit, does it matter if I retain the 6 or change over to v8?
