Need help installing PU's in Tele HH

I recently bought a Tele FMT HH. Love the look and feel of the guitar, but don't care for the Enforcer pick-up's and would like to change them out. I would like to put in a set of Dimarzio's, probably the Air Norton and Air classic.

From what I've read I need to order F spacing for the bridge p/u, but how about the neck?

Also, the pick-up's in my tele have two adjustment screws on one side where the after market p/u's that I've seen only have one. Can I install a different mounting ring (if that's what their called) with only one screw instead of two or do I have to find p/u's that have the two adjustment screws.

In either case can anyone tell me where I could purchase either. The mounting rings are held to the body by four screws, one in each corner, so I would have to have something that match the bolting pattern/spacing.

Any help would is greatly appreciated.

I don't know of any other maker that uses the three screw pattern.

This place has just about everything (http://guitarpartsresource.com/guitar_index.htm), specifically mount rings (http://guitarpartsresource.com/covers_plasticrings.htm)
