Will I need to make modifications to the housing or are the 4cyl and 6cyl the same?
Will drop right in.
Not totally true, some minor grinding needs to be done on the gear slots on the flange, especially with 5:29 gears. The slots need to be deepend and widened a bit. No big deal and it makes the 3rd slide in a lot easier.
