We finally got the convertors in, but by that point we needed a truck and worked a deal with the local dealer on a new truck to take our old truck off our hands. This happened a week before the parts finally arrived. My husband went to pick up the old truck to give to the dealer as a trade, and it still had problems. Husband managed to limp it home, and gave it to the dealer to deal with. We attributed the problem with the fuel pump, so either that failed and caused the convertor to fail, or we just wasted three months of waiting for nothing. Either way, we have a nice shiny new F150 to play with. I must say it is a much nicer truck. We got the old truck paid off plus an extra grand, so we didn't lose money on it in the end. Luckily my husband gets a vehicle allowance each month to offset a new car payment. Whoever got the old truck got a great deal as now it has a new fuel pump, and convertors, and 50k on it. Our nightmare is over..good luck!
