Dany, to clarify this, you need STOCK Ford bellhousing, motor mounts and headers mayby 'cause you're reverting to Ford power? Note there were two bellhousings possible (a rare early 4-bolt & later, more common 6-bolt plus 2 large allen bolts hidden inside) depending on your ZF, and two different factory headers. The OEM stamped-steel 'headers' usually cracked from differential heat expansion as they were only two steel stampings with tubing sandwiched into openings and welded. If you extensively rewelded them, they cracked next to the new welds... not recommended. The almost-equal-length 'GTS' conventional style headers work much better.
