Swap Slant 6 A833OD to 360LA Parts List?

Hey everyone, i have a 1980 D150 2wd short box with a Slant 6 and a A833OD 3spd. I'm swapping out the 6 for my 360LA
engine i built, but i want to keep the manual transmission, is there a bellhousing adapter plate kit available or do i have to search for a small block bellhousing assembly?
Are the flywheels, clutches etc different?

Any advice on this subject would be greatly appreciated, first time doing this.
Thank You, Ashton.
