Engine/Transmission (1998.5 - 2002) NV 4500 to NV 5600.

I have a 5spd know and was going to get a SBC MCU92 con OFE with the 13" flywheel. Will it work if i changed to a 6spd? Or do i need a new clutch?

I have the same OFE you do, all you will have to do is get a disc, the input shaft on the 5600 is 1-3/8", 1-1/4" on the 4500. I have to get one also, got the 5600 ready to go in, if I ever get time!
