What bellhousing for a 4 speed in a slant 6 Duster

If I remember correctly, the A-230 3 speeds were drilled with dual bolt patterns. If you have or find a OD bell housing you may be able to get slip rings that drop down to 4.80 or 4.35 bearing retainer size. QuickTime bell housing for a small block will fit a OD trans but comes with slip rings. This is what I "know" because I have a 4.35 slip ring behind a 360/414. You can get an OD bell housing from a 70's - 80's Dodge Ram.
