Rog, thanks for this very helpful link. As seen on their page they are the guys who did all the conversions for MMC Mazda gearboxes. I am looking forward what they will write back re the 6 speed box.
BTW I think their prices are very reasonable if someone would think about a swap from a Ford transmission to a Mazda one including all part plus prop shaft for under 3.000 GBP.
