How Hard Is It...........

How hard is it to swap a 10 1/2 inch clutch setup in place of a stock 9 1/2 inch set in a '65 Barracuda? We have a lakewood small block scatter shield that we plan on using. How hard will it be to use that? Also we have the 130 tooth 10 1/2 inch flywheel. Would all that I need is to shorten the Z-bar to make it fit?

The reason I want to do this is cause the car needs a complete new clutch kit so the trans is going to be dropped and I already have these parts so why not?

Thanks
