Bellhousing clearance

This question is some of you who changed to a 10 1/2 clutch on your early. How much room did you have to make in the tunnel.Did it fit without trimming? A lot of info has been all over the place on this subject. Engine compartment is done and I'm getting ready to clean up the tunnel and prep for the larger bell. It is a 360 to 833 combo going in with hydraulic clutch. Thanks for any advice in advance, Chris
