are you sure your up to doing a r&p swap? It's kinda a big deal, you'll need a press, dial indicator, big hammer, and plan on a good 8hrs to get things together. Get a friend to help you run a pattern, make sure you do it loaded and take your time.
Oh yeah, this is the most important part... dunno if it's mentione before because I didn't read all that baloney.
Make some dummy bearing from your original bearings! Ittakes about as long as pressing bearings off once and will make your life SO much easier. Good idea to have the same brand, but if the brand is different you can measure the height of both bearings and get a pretty good idea of whats going on. Don't assume that because your bearings are whats called for that you'll run the same pattern.
