The L, H, R, or P for 1970 trim codes reflect trim grades;
L = Low (Plymouth pattern vinyl and more, see L6X9 below)
H = High ( vinyl )
R = Leather (Dodge only, leather bucket seat inserts and carpeted lower door panels) ( H5 cloth interiors included the carpeted lower door panels as well)
P = Premium - (Plymouth only, includes leather front seat inserts and overhaed consoletete)
The L6X9 code is found on A93 Coupes, both Challengers and Barracudas. Challengers with L6X9 recieved Plymouth seat upholstery and rubber floor matting instead of carpet, but A93 cars could be "optioned up" with carpet.
Coupes are cool, I have personally only seen two so far in my lifetime. :beer:
T/Ake care,
