I'm about to finish my t56 swap, for those who have done this what did you you use for your slip yoke / driveshaft? It seems all are 1310's, my rear is a 1330. I would like to run 1330 front and rear but it looks like I will have to do a 1310/1330. How hard would it be to deal with the driveshaft and dropping the tranny if I were to use a slip yoke that doesn't have the U-straps and just stick with 1330's?

I just went through this when I purchased my TKO 600 kit through SST and they included 1310 and 1330 UJoints on the driveshaft.
One thing they stressed was that I could run into clearance issues in the tunnel running 1350’s front and rear or even 1330’s on the front.
I talked with Mike Dyer who is building my rear differential and he also told me that 1350 may cause clearance issues depending on the year as some tunnels were slightly different.
Both SST and Mike Dyer agreed that on a street car I shouldn’t have any problems running the 1310/1330solid Spicer U Joint set up on the drive shaft and the real issues come at the half shafts where I’ll be running 1350 solid Spicers.

I think the issue is which transmission you use. With my Richmond, which is the same length as a Muncie, my 1350 tranny yoke has plenty of clearance. I found a nice compact yoke from Moser. Any transmission that goes farther back in the tunnel will have issues the farther back it goes. Was surprised how much clearance I had. TKO’s and T56’s will probably have issues with a 1350.
