I'm getting ready to do an engine swap on an automatic 96 gt. I have PI heads on the original engine and I've developed a knock that I suspect to be a rod bearing. Anyway, I'm dropping a PI engine from an 02 in. It's a Windsor engine and therefore has the 8 bolt crank. I picked up some valve covers and flex plate at my local salvage yard. The engine was just sitting by itself but was in the truck section so I suspect this engine came out of an F 150. Considered myself pretty lucky as I didn't have to pull these items from a vehicle. But I'm concerned about the flex plate. It is 14.5" 164 tooth but the torque converter bolt pattern is 11.5" and I think the mustang is 10.5". Parts inquiry at various parts places all call for the same torque converter for F 150 and mustang so I'm a little confused if this flexplate will work or not. Can someone shed some light on this for me? Thanks
