gidday guys. questions about 3sgte

gidday, i have a few questions about converting a 3sgte from 4wd to rwd.

is there a rwd box that bolts strait up and everything works, or do i need to get a custom belhousing made up and use a old supra gearbox or somthing?.

the engine is turning oer but there is no spark? ive checked the points and spark plugs. . . but don't know much about these engines? so any info about geting spark would be grate thanks:D.

cheers
