No not mine, just saw it on the local craigslist. I did a little internet checking on the case numbers, appears it could be a Saginaw trans from a Vega. Supposed to still be a good trans and has a lower 3.5:1 first gear was what I read online. If someone is seriously interested I could probably be persuaded to wrap it up and strap it on a pallet. You'd have to make arrangements with a shipper and I could drop it off.
If it is for a Vega I doubt it would live behind a 350 let alone a 455 I have very limited access to websites from work.
