The slant will need a 122 tooth flywheel, the 318 will need a 130 tooth flywheel. The clutch for the 318 will be a 10.5".

As above, It is the bellhousing that dictates the flywheel. He will have to get the special parts from Brewers Performance or Passon Performance to put the 10.5 bellhousing into an early A Body.
