[DeTomaso] Looking for a steel zero (intermal) balance flywheel.

[Ken Green]

I bought a McLeod Street Twin, but it has a 157 tooth flywheel.  I'm looking for a high quality steel flywheel that is thick at an 11 inch dia where it needs to be drilled for the pressure plate.  A lot of steel flywheels are machined on the back side to lighten them, and are thin at or near an 11 inch dia.  
 
If someone has replaced a good steel flywheel with aluminum and wants to sell the steel flywheel, please email me.
 
As far as why steel, it looks like all the 164 tooth aluminum flywheels have 11 inch dia friction surfaces making it impossible to drill them for this particular clutch.  I also want the angular momentum of a steel flywheel for the specific engine and gearing I am using.
