[Healeys] Uprating early 3000 disk brakes

[patrick williams]

A few years ago, Magnus Karlsson wrote an article in AH magazine on
upgrading early 3000's ( Girling 14 calipers to Girling M16 calipers).  The
advantage is that you get bigger calipers + pads.  The mounting holes are
spaced 3 1/2 in for both.   I found some M16 calipers dirt cheap on line (
they're off of early Mercury Capri's).  However the mounting bolts appear to
be 12 mm which is not the 7/16 in. for the girling 14.  My questions for the
list are:

   - Have others done this conversion?
   - what's your mounting bolt solution?  Custom make a bolt or sleeve the
   caliper?
   - Is the conversion worth it? with
   - Should you use early or later (BJ8) disks?
   - Thoughts or data on offsets  to center caliper on disk.Have others done
   this conversion?
   - If I sorted through this upgrade, would others be interested in it?

I realize that the fluid connection needs to be modified to metric but that
is pretty straightforward.
I'm also planning to install a brake booster into my car to improve overall
safety.
The collective wisdom of the list is appreciated.what's your mounting bolt
