10.5" flywheel for a slant 6?

My 6pak RR has the 130 tooth flywheel, which is correct for the aluminum bellhousing and the 10.950” clutch. With the Centerforce clutch and no over center spring, it shifts like a breeze.
@kesteb - I used a big block scattershield, like Hyperpak did on his recently completed Lancer wagon. I agree with those who told you that putting the heavy cast iron truck bell housing in your Dart for the 143 tooth flywheel would require a lot of metal work. That thing is a beast both in size and weight.

@gregcon - if your referring to the 143 tooth flywheel the only passenger car bell housings for it were big block passenger car, typically 440 6Pack or Hemi but I think optional on other big blocks.
