Here's another trick Cook often uses in his racing transmissions. On the right is a standard, OEM replacement bearing. On the left is a used max-load bearing out of a NASCAR Sprint Cup transmission that has been used less than 500 miles. The Cup bearing is better in every way than the stock piece, and the price for a new one reflects that. But Cook has many contacts and can find these bearings after they have been replaced in rebuilds-it's one of the perks of operating in the heart of NASCAR country. The bearings are still practically new and Cook can sell them cheaper than you can purchase a new OEM bearing.
