hi i have a tko 600 on a 351c much the same set up as yours. i used a lakewood bellhousing from an early mustang, and bought a short input shaft for the tko. alternatively you can use a spacer plate behind the bellhousing to the gearbox. make sure the bellhousing you have h=is a tight fit on the gearbox input shaft housing otherwise once you have dialed in the bell you will not get it true.
