Got my Megajolt working!
Fired it up today - seems to be working just fine. Also, my CA/Smiths/Greengauges rev counter is perfectly happy with the MJ tacho output, which is a
relief. Just waiting for some vacuum pipe to arrive, then I can complete the installation (oh, and the shift light - but I've got to create a
mount for that).
Just one oddity - the tacho meter on the PC configurator display shows around 500rpm when the engine's stopped. This isn't a problem of
any sort, as it matches my own tacho exactly once the engine is started. Perhaps it's some kind of 'feature' in the software!
I've also removed the old dizzy and replaced it with a turned plug - what a lot of room there is on that side now! 
Thanks for all the help I have received...
David

Funnily enough I was looking at our megajolted Kent yesterday and was thinking the same thing. Once the dizzy and fuel pump are removed, there's
plenty of room on that side

I want to do this to mine. Any hints/tips/instructions on reducing an existing dizzy to its smallest size?
Many thanks, Andy

I didn't do it that way - I took the clamp off the bottom of an old dizzy, then turned up a bit of steel on the lathe so that it was the same
diameter as the dizzy's shaft. Turned in a groove for an o-ring, then used the old clamp to hold the bung in place. I put an over-sized bit at
the top of the bung to ensure that it couldn't fall inside the engine, even if the clamp came loose.
Here's what it looks like now:

I hate to ask but I will anyway!!! 
"How did you drive the oil pump as this is driven off the bottom of the dizzy on a Pinto??"

'Cos it's a crossflow!
The oil and fuel pumps are driven independently from the dizzy, so it can be removed without causing problems elsewhere. The dizzy and the oil pump
use the same gear on the cam, but totally independent of one another.
Good point though - if anyone else is thinking of doing this on any engine other than a crossflow, just make sure that it won't cause problems
elsewhere.

Here's what the engine bay looks like now, just in front of the scuttle. The MJ box is on the other side of the firewall.
