Have been nutty-busy, of late, so not much time for JL stuff, but here is an update on info(s):
On the speedo cable:
But as I read the spec sheet, the gearbox comes with a new speedo cable with the correct flange on it anyway. So- no angle drive needed at the box, it seems and a gear reducer can be put in line to calibrate the speedo, per response to my inquiry via Richfield Speedograph (am attaching their attachment, here):Recalibration sheet page 1 only.pdf (71.1 KB)
Many thanks for your enquiry.
From the information given you have a Ford type 9 speedometer connection on your gearbox.
We do an angle drive that fits this connection in different ratios ( our RGB1030 series.)
Once you have your gearbox fitted if you could fill in our re-calibration Form ( copy attached ) and
Return this to us , we can work out the ratio you require, which hopefully will mean that you do not
Need your speedometer to be re-calibrated at a later date.
I hope this helps you but if you have any further questions I will try and help you.
Regards

Latest (I have furthered the inquiry,since, yet no response, yet) from Guy Broad, purveyor of the Broadsport box (good news for the V12 faction):
Our gearboxes use the 5 speed clutch plate as fitted to Jaguars aprox 85 -87 spec , still easily available from AP Lokheed .
But I doubt you can wear one out in 75000 miles of normal driving .
We give details of fitting and the gearbox is 108mm longer than any standard [ not 2+2 cars ] gearboxes . all 3.8 or 4.2 cars roadster or FHC.
We do have new prop shafts in stock or you can have your old ones reduced . a new prop is about £ 250.00 GBP in stock.
We do also supply for the V12 cars as the case is already machined for the 2 side studs that take the clutch slave cylinder as on all V12 E ‘s .
We supply a rear mount bracket that picks up the OE rear pin bolt on all manual V12E . the gear stick comes in the OE place on all cars , so mods to tunnel top or interior trim.
It’s all quite an easy job on all the cars and any half descent mechanic will have no issues as to fitting .
Our speedo cable does not use an angle drive , it is held direct into the box with a circlip. It goes under the floor and not at the side like old OE gearboxes from Jag. Easily accessible from under the car at any time.
There are no variations on speedo drive gears as there would be way too many possibilities for axle ratios etc. the factory fitted [ from XK to E type ] 3.64 ,3.77,3.07,3.31,4.09,3.54 as variations of standard fittings !
So, basically you would need to re-calibrate the speedo when all installed .
I hope this answers most of what you need to know
Soooo…it looks as though the LWB cars don’t need the frame cutting/welding (the “chamfer”) but I still have a lot of questions (most posed, already and awaiting return response).
Bottom line is, I am still going for it, as of now, it is just a matter of time, money and info to be relayed, methinks.
More later, as Harvey and Irma are making me too busy.
