Granada type 9 (with long primary shaft) gearbox

Help! I've got one of the above gearboxes which I want to connect to my 2 litre pinto. The primary shaft extends about 30mm beyond the front of the bellhousing which will not mate up with the engine block. I have read a lot of threads on various sites most of which say 'Shorten the primary shaft with an angle grinder'. None of these threads indicated how much should be cut off (no dimensions quoted) and furthermore none of the threads appeared to have been submitted by someone who had actually done the shortening and with what success if any.

Has anyone successfully fitted one of these longshaft boxes by whatever method and with what result? If someone has used the angle grinder method with a positive result it will be helpful if they can tell me the dimensions of the piece removed and whether any other alterations were necessary and are they happy with the results?

You'll want one of these, with the extra machining for the stub shaft to locate into if you have the heavy duty gearbox, and 4 longer bolts to match.

http://www.rwdmotorsport.com/adapter-plate-for-ford-bellhousing-to-2-8-ford-gearbox.html

It will save you the effort of shortening the input shaft, and depending on setup, a shortened input shaft may not correctly engage the clutch splines anyway.

If you are considering shortening the shaft, the v6 is 32mm longer than normal and the splined section is further up the shaft by approx 10mm so that may want grinding down as well.

Have a look here for overall dimensions.

done it when putting a T9 onto a essex V6, still on there now and works fine. Cant remember how much was taken off, but was simply done with a disc cutter and tidyed up after!

to my mind the spacer/adaptor above (or similar - caterham also used spacers) is a better/neater solution, its also easily removable if your plans change in the future

here's the dimensions of the std. short version:

are the Granada ratios any good for a kit... better or worse than the standard type 9?

My thanks to all who have taken the time to consider my questions and bothered to reply. It does seem that more opt for using a spacer and one even then removed some of the primary shaft. One kindly offered a spacer which was unfortunately too thin which again meant cutting the shaft.
I would like to do one thing or the other rather than both. It would be helpful if someone has an RDS Motorsport spacer they no longer need, or can someone advise of the exact length of shaft to remove?

Gear ratios on V6 type 9ís are better.
Standard. V6
1st 3.6. 3.36

2nd 1.96. 1.81 the gear that lets the V6 do 60 in 2nd

3rd. 1.37. 1.26

4th 1.0 1.0

5th. 0.82. 0.825

You donít want a diesel or P100 box

Both of the above boxes have totally useless ratios with first gear being almost redundant being way too low . They also have the long first motion shaft.
If in any doubt remove the top cover and count the teeth on the gears

Some Transits has a rare short 195mm input shaft just to confuse meters further.
Even the V6 box would benefit from a longer 1st gear
I have run V6 boxes with spacer for some time using a 3.9 diff

Is the spacer that you are using 20mm as is the RDS type?
