My Bristol

[Janne]

I hope you do not mind me saying this, but you have a long time before you can start thinking about the interior. A lot needs to be done, if you want to do this restoration properly. If you do it badly, you will damage the car more than restore.
I personally think you should try restoring something more simple, like a motorcycle, first, so you get used to the tools etc.
If you restore an old Harley, and do it well, you can make some money, which you can use in restoring your Bristol.

As you live in the US (correct?) you can get all Mopar parts locally, including the resto of the engine and conversion to a 6 speeder.
Not sure why you want a 6 speeder, the engine would be very happy with less gears.
