4l60e Driveshaft question

[knockoutgasser]

My last major hangup before doing my LS swap is the drive shaft. I keep coming across 4L60Es with fixed yokes for a two piece shaft set up. MY 75 LWB is a single piece shaft with a slip yoke

So after much searching before I posted this, it seems I have to do one or two of the following
1. have to find a slip yoke 4L60e
2. Swap tailhousings on the 4L60e i have if available
3. Install a two piece shaft set-up and carrier
4. Get a custom driveshaft made with a slip built in from the Jeep shaft builders ($400)

So are the tailhousings interchangeable on the 4L60e without having to tear into the thing and change output shafts?
Any suggestions guys?
