Which bellhousing?

I had considered that but didn't have any way of getting those measurements, I'll have to look into this and see if it's possible. Would be a hell of a lot cheaper and easier for me to just swap the bearing retainer since I'd really like to keep the O/D for highway cruising. Great info!

Also going to see how much it would cost me to have my retainer turned down to 4.807 and that the cheapest route would be.
