Production numbers 1973 duster

I have a 1973 Plymouth Duster VIN VL29B3B427235. I have been reading several web sites on the internet, and none of them show the 198cid slant six as an offering for this year. I have the car currently up for sale, and now I'm wondering if I should sell it, although it probably isn't rare, it is probably a lower production car than I think it is. Can anyone help me with figures for this car? The fender tag from top to bottom reads as follows: Line 1: JY3 11 EK2, Line 2: JY3 D2Y4 000 403 118425, and Line 3: E22 D14 VL29 B3B 427235. It is also a radio delete car and from the paint codes is Honey Gold exterior and interior. It as also D14 3-speed manual on the column. It has factory rallye wheels, manual drum brakes and steering. Any help would be appreciated......thanks.....Steve
