I have a XR-7 that was built, according to the plate, in 4/73. I wanted to replace the torn up veci sticker on the valve cover; but when I go to Mustangs Unlimited they show 3 different stickers for a 351C 2V AT car. One is LATE, the other two are EARLY, just no indication of how early early is, and what the distinction is between the early decals other than one says Ignition Timing is 6 BTDC the other 10BTDC

What is considered early- or more directly what sticker (ignition timing) is correct for my April cat?

4/73 would be considered late, maybe even very late. Production typically goes from July to July so a 4/73 car was made in the last 90 days of production for the model year. Hawkrod
