Need help NV4500 to 454

For anyone out there who has switched their old square body over to an NV4500. I currently am attempting to drop my old TH400 out of my dually and put in a 96 NV4500. I have the trans, bellhousing, hydro clutch pedal, the slave cylider and master cylinder. The guy I bought the trans from didn't know how to unhook the lines so those are cut and ruined. The truck is 2x with a 454 and has the brake booster/power steering setup. I have done conversions on small block Blazers with the AA adapters with the old Z-bar clutch systems. So this hydraulic clutch is new to me. Any help with hooking this thing up would be greatly appreciated. A line for parts would also be helpful. Thanks to anyone with experience with this.

Hydro clutch was offered in squares in...84 or 85 and newer, going to need a pedal assembly and to drill some holes in firewall to mount clutch master cylinder. I am not familiar with the internal slave style NV4500, but IIRC there is a tool to disconnect the lines.

I have a '93 MY NV4500 for my '83 and I've collected some info on the swap. One of our other members, DirtyLarry, did a similar swap: his thread.
