My "new" '74 Duster- or why I need a project like a hole in the head

I did read to whole thread and you were going to get the Wilwood 14" kit, but ended up with dr diffs 13" cobra kit. Is there a reason? Like it didn't protrude out further than the 14" kit etc?

I was planning on using the wilwoods originally because the first set of wheels I bought had a 26mm offset, so I didn't have the space to give up the 3/16" that Dr Diffs kit adds. But then I figured out that I could fit 295's out back, and that I had calculated the offset in the back wrong. With the RPF1's I had the room up front, and that wilwood kit costs almost $1k more than Dr Diffs kit. Plus, the Dr Diff kit uses OE rotors and calipers, so if I need parts later they should be easier to come by.
