Re: 4 lug to 5 lug conversion
I just did the conversion last week, and assuming you already have rear disk brakes, it's fairly simple.
You will need:
rear v6 hub bearing assy, rear disks (may reuse calipers and pads)
front v6 hub, new bearings, v6 calipers, v6 discs and pads(bigger than 4cyl)
Dorman makes fairly priced hubs it's what i used.
do a search, there's a few DIY about it.
axles will fit without issues btw
