OOOH, this is weird- not mine -factory 360 Valiant 4D !!!
Yep, that almost got me too, but I looked closer and saw they used a lower case "L" in the listing.
L was used in 74-76 360 Dusters and is the 4 bbl code.
IIRC J is the 2 bbl 360
Rallye red
Certified speedo
A/C
Looks like straight, almost rust free body
Still has air cleaner
Too bad it didn't get bucket seats like a LOT of 4D cop cars got, even F body.
This is the kind of oddball stuff I LOVE about Mopar.
