Guys have significant trouble using the diesel ZF6 behind the IDI.

Not even sure where to begin with the gas version.

Personally, I very much liked the ZF5 when I drove IDI's. I plan to use one with a 6BT some day. Just shift the tcase to low range when you want a creeper gear.

Only issue is my truck is a stock zf6. And i use a pto with it

I read about redrilling a 7.3 idi flywheel to fit a ps 7.3 pressure plate and disk. Thats fine. Just need to know for sure.

According to southbend clutches the zf6 used with my stock motor....5.r triton... Is the same input shaft as a zf5 used with the idi

If not possible to us my stock zf6.....what about changing the main case?

I'll have to suggest you ask the guys over at oilburners. They know it better than I do.
