As far as I know they were all r150s. These are not popular due to the chain driven case. These cases are not bad they are just difficult to go duel cases with. If you are planning on running a single case the simplest thing might be to use the r150 case with the r150 tail housing. This could save you needing a 400$ adapter. These came behind 3.0L v6s. The 3.0 is not a popular motor and often has head gasket issues. If you look around you should be able to find someone parting one out for cheap.
Again I am just assuming this is all possible so I would recommend doing further research before buying anything. If you do this swap please post back with the results so the next person can find the info.
