OK I've got a 89 3500 excab drw w/454 and sm465 it's a 2wd. I'm swapping in a 1996 model nv4500 does anyone know what I need to change my truck from the hydraulic slave cylinder setup to the hydraulic throwout bearing that the nv4500 uses. Also any other problems or useful tips tricks or parts a guy might need to get it done. Thanks
