Alright Dan, cracking progress mate. The Gasket your talking about is just a sort of dust cover that sits at the bottom of the box. The gearbox sits a bit lower than the sump and there is a big gap without it, so it would allow road dirt and water up if not fitted. If the VR one is fitted in a similar way but you dont have the cover, I'm sure you could fab up something that would suffice mate.
the one out the 8v box does fit, kinda. its a couple of mm too long at one end so i might just snip a little bit off then bolt together!
i was going to give the bay a good clean and tidy up but dont think i have the time lol
and cheers sean there still a fair bit to do, however we have broken the back of it, just got to fit all ancills to the lump, change drivers rear mount, fit box to lump and get it all in. tempted to change the clutch plate and flywheer? hmmmmm lol
