T18/T98 swap?

I’ve been looking but don’t see any options for connecting a MOPAR engine to a T18 or T98 gearbox. Am I missing any?
Otherwise seems like it’s a matter of reaming out a MOPAR bellhousing for the 4.684 input bearing cover, drilling mounting holes in the bell, and being ready to chop the input shaft and use the shoulder mounted bearing instead of a bushing. Am I overlooking anything?
