Would a '88 ZF5 truck have the BW1356?
I've been doing a lot of thinking and not sure if I want to do the ZF5 swap anymore. Think I'll stick with the auto and do the RSK and Dana 60 in the front.
Now I need to find a 4x4 E4OD tranny though...

yes, the '97 manual is a ZF5. They used the ZF5 from '88-97. In '99 they switched to a ZF6.
I'm not sure what interal components you can upgrade on the ZF5, but a good clutch from Valair will hold up to a lot of power. The Kevlar/Ceramic single disc is rated at 400 or 450 hp (IIRC) and the ceramic/ceramic single disc is rated up to 550 or 600hp.

I'm really torn about my swap...
Swapping in a Dana 60 front is a given, gotta have 4x4.
Part of me is saying that sticking with a auto is much easier, less modification, but expensive for a good stout trans.
The other part of me knows that I would be much happier in the long run with the ZF5, even though it will take more work to swap it and get rid of teh auto stuff on the column...

What do you think my power is?, pretty stock, with the riffraff intake and a 3" downpipe. I don't plan on going with huge power so I'm guessing the 400 to 450 hp clutch is a notch or 2 above stock? I have no clue what my HP and torque numbers are bone stock, that and I'm at 6200 foot elevation. I heard the turbo makes up for power loss due to altitude.
Do you know if the slave/master are the same for an '88 and a '95?
I already have the ZF5 and t-case, so I'd need a SMF, clutch, slave/master cylinders, and pedals. So probably less than $1,000 for all the parts I need.

Definitely do the SMF!
DMFs suck, I'd like to kick the engineer in the gonees who thought it up.
I don't want to spend the money to build a good E4OD so I'd go manual everytime.
Now if I could just get my Wife to drive one.

Hey i am tossing around the idea of doing the swap in my 95 psd f250 excab lb 4x4. I have a 93 excab lb 4x4 donor truck at my disposal. I have read that it has the 42 ZF and the psd used the 47. Do you have any advice?

You're right about being able to do it whenever. I guess I could put a little black-out piece over the PRNDL part on the dash and either cut off or unbolt the shift lever from the column and cover it with a manual column piece. I just hope that putting in the clutch hydraulics isn't too much of a pain... and the wiring. I hate wiring.
