833 18 spline to 360 question

[Magiver]

I'm resurching the possibility of installing a b body 833 18 spline to a 360 for a 68 Dart.
I have only found 10.5" systems for the SB and only 11"clutch disks for the 18 spline.
Is this even possible?

The Centerforce PN. DF 381810 is a 10 1/2" 18 spline friction plate.

You can get a 18 spline clutch disc in the 10.5 diameter.
Tail shaft is longer on the b-body trans. Shifter mounting pad is also moved.
Transmission mount is the same.
