Clutch for 70 10 1/2 inch bell housing

[RRunner70]

Got a problem not sure what to do about it. Have a 70 roadrunner project making it a 4 speed with a hemi 18 spline trans I have the Aluminum bell housing for it wich had a 10 1/2 clutch (68 69 had a cast iron bell housing with a 11 clutch). Any way I had this same 10 1/2 set up before in another car and loved it but it seems as if the clutch of my choice Center force I cant find anywhere in 18 spline and 10 1/2 inch, any one know where I can get one ? Also how many teeth flywheel should I have for a 10 1/2 clutch not sure if im have the correct one or not.

10 1/2" flywheel has 130 teeth, 11" has 143 teeth. I am by no means an expert but I've never seen a 10 1/2" 18 spline clutch. If you have your heart set on that clutch, I'll trade you a 23 spline trans for yours! If you want to use that trans you may need a new bellhousing.

Ok correct me if im wrong 1970 they switched from cast iron to the aluminum bell housing and the aluminum bell housing had a 10 1/2 clutch and that would make any 1970 440 4 speed or Hemi 4 speed a 18 spline 10 1/2 clutch.
I may have to get a 68 69 cast iron bell housing to get the center force clutch I want. Or is it possible to fit a 11 inch clutch into the 1970 aluminum bell housing?

Call Brewer's performance, the 4 speed experts. I'm sure they can give you all the info you need.

Found a few places that have a 10 1/2 18 spline clutch but not a centerforce. Breweres shows discountinued. This place has one but unsure of the clutch quality.

Keisler sells an Aluminum bellhousing that will take both 10 1/2' and 11' flywheels as it has both starter locations.
Hope this helps.

I know this is an ancient thread but the centerforce part # in question here is DF381810

Chrysler used a 11" pressure plate on the 10 1/2" flywheel 130 tooth. Used special star drive bolts to clear bell housing. Anyway this is the factory setup in my 72, 18 spline clutch disk.
