I suffer from cars on the brain!
It seem that these were discontinued some time ago, but I am finding them again listed by EQ in Las Vegas. They sell them though their eBay store, including the LA intake bolt pattern on a Magnum version. I thought I would include the links to what I found if it will help someone looking for them. I would normally look into this deeper for myself, but ended up going a different direction when these were not available at the time.
