Hey all, My uncle is buying a 67 mustang convertible and asked me to check out the data plate. I've punched the warranty number and 7R03X231864 data code 76A T 2A 20U 72 D 4 and no matter where I check it fails with the X in the warranty number and the 4 in the data plate. Any ideas on what...

i got a 351w out of a 1996 f250 that i want to put in my 1967 mustang. i want to keep the EFI instead of carburator. my question is how/ what do i do to the harness out of the f250 to make it work with the 67? its my first time doing it.
