His post is 9 years old but you bring up an interesting point Jimmy. Something I've been throwing back and forth with a couple of members. With his car being an 11C build and the vin at the oil filter, and yours a 10B and the vin is on the pad.
Mine is a 12D and the vin is at the oil filter as well. At some point in that Nov/Dec time frame Norwood made that transition. I've seen 2 other cars very close to my build with the vin at the oil filter as well, that tells me this practice was getting pretty consistent by then.
However the JM book briefly mentions the change happens sometime in January. I tend to believe it was happening a little sooner as the evidence suggests.
