Hey lads, i have just purchased a 63a box and was wondering what people thought about getting the larger 63a clutch plate on to this fly?

Most people say that the small ridge you can see will have to be machined flat for the 63a clutch. What does everyone think? Any other problems i may face?

I may have to get another flywheel made up, if there are any other problems any one can see me having.

Cheers
