For those of you who missed it the first time around.

AND FOR THOSE PEOPLE WHO THINK THEY KNOW ABOUT THIS THINGS EVEN THOUGH THEY 
HAVE NEVER SEEN THE BOX IN THE METAL THE TECHNICAL NUMBER FOR FORD (UK) IS: 
01922 725551

The Merkur 4ti is basically the same as the Sierra box Frontline and others 
use in all their Ford based Spridget 5 speed conversions.  However, I think 
only Frontline are the only person with a kit to hang this box on the back of 
a 1500.

Yes the Merkur box does have different ratios and they are closer than the 
standard ratios eg: standard 3.65, 1.97, 1.37, 1.00, 0.82 whereas the Merkur 
are 3.36, 1.81, 1.26, 1.00, 0.83.  If you compare this ratios to the 1500 box 
I can't see there is a problem.

No the box will not fit because the Merkur box is designed for a vee 6 so has 
a longer input shaft.  The shaft can be shortened (not recommended) or the 
input shaft and corresponding gear can be swapped with the 4 cyl (UK spec) 
shaft and gear - obviously this puts up the price and entails a full gearbox 
rebuild.  However, some early boxes may not have the slightly closer ratios 
anyway.

Minor difference in gasket but otherwise the changes over the years to the 
boxes are not going to cause a problem.

If you can find a box and are prepared to spend a bit of time and money you 
will end up with a really neat conversion - oh and don't forget the quick 
shift gear lever.
