if you check 1uzfe.com, there's a guy who's put an aw11 rack with aw86 steering column into a te27. he had to shorten the rack ends, so maybe it would be easier to put into a ke3/5
fook's told me about people using racks from little fwd cars like ford meteor or something
at the very least, you're going to need to weld mounts onto the crossmember, and either use a different steering column, or make up a uni to go to the stock steering column
measuring time at the wreckers, call an engineer before you spend anything
