That car has those awful big bumpers on it while a proper 1967 should have the much more attractive chrome bumpers. They should look for the proper chrome ones - so much better! Call Tony Handler or Oregon Crewe Cutters, or perhaps
www.britishpartsco.com for a set. Also keep in mind that this being a RHD, it's ultimately worth about 20% less than a comparable LHD model in the 'States. One should never, EVER treat a Shadow or T-Type as an investment. They're virtually worthless.
With that outta the way,

while the trans is out, call Alber's Bentley Zionsville in Zionsville, IN with the following list of parts:
Trans overhaul kit (billed out piece by piece, welcome to Rolls ownership!)
Rebuilt Accumulators
Accumulator check valve kits
Caliper seals
High pressure brake hoses, all around.
That's a good start.
They're going to sell you lots of little washers and seals that go with each of those jobs - don't skimp out and get everything they tell you you need. This is not an easy car to recommission, the braking and suspension systems are complex and expensive to rebuild. A car that sits is a car that dies. So good luck.
And do us all a favor, when you get her up and running (worth it if you are going to keep the car) don't put the F@cking Grey Poupon in the console. Or the stupid Chauffeur's cap. That's just seriously un-clever. And don't rent it out for weddings, that's trite. Just drive it, it's an experience like no other car in the world.
