[455Turbo]

I think I have what you need. It uses a 5 pin module, has centrifugal and vacuum advance, and has a 4 pin square connector for the computer.

I have a computer and wire harness too if you're interested.

You could use a "standard" pontiac HEI distributor with a MSD 6A and Boost Timing Master instead.

Here's a pic. It's a bit rusty but everything moves. I would be happy to recondition it for you or sell as-is.
