Fellow Minoids,   I am restoring my 1967 Morris Mini Cooper S.  I am trying to devise a vapor barrier that attaches to the bulkhead behind the 2 SU carburetors.  I would like to know what others did to halt the vapors from intruding into the car.  I currently have a 10" x 10" section of vinyl cut out for coverage of the speedo opening with a possible Velco attachment mechanism but I don't like the way it looks.

The cars of that age were sealed here by using putty around the actual instrument binnacle, where it fits to the bulkhead/ firewall.  It works relatively well but obviously needs to be done thoroughly.

Later cars with offset instruments had a much more substantial metal plate over the rotodip hole, again with sealing putty.  I've always wondered if you could fit the metal plate to cars with the central speedo.  Possible I'm sure, but would be awkward!

I cant  remember if the cars of that age have the small hole in the vertical face of the cross member don't forget to fit the plug to it.

If it's all fitted back as per the factory you don't need a vapor barrier, Just make sure the binnacle is sealed around the edges and all the grommets are fitted and in good condition. The only reason for additional "barriers" would be for noise.

I re-used the metal plate when I converted to central instruments on my 89 car - just needed a hole cutting for the speedo cable

Nice job, it's the best way to seal the bulkhead in my opinion.
