The correct term in 1970-71 was a sunroof and not a moonroof. The moonroof term came into use in the mid-70s when Chrysler started to heavily promote this option in the Cordoba and B-body line.

The 69 Charger was the first Mopar to have this option. There were about 130 R/T models sold with it. The roof panel was smaller than the one used on Challengers. You could order the option on 70 and 71 model Chargers too.

Looking in both the 70 and 71 new car salesman pocket price guide (a little price booklet with all the list prices and options and packages for Dodge salesman to price new cars for customers), it is referred to as the M51 power sunroof option. All of these roofs were power and none in this period (even for B and C bodies) were manual. The price of this option was about $450. It went down after the 1970 model year by about $15 or $20. The option price was the same for a Challenger or Charger.

In 1971 Plymouth offered the M51 sunroof option on all of its B-body models.

The M51 option wasn't offered on Cudas until 1972 and that was the only year it was offered on the Cuda. There were a little over 30 1972 Cudas sold with the option (I can find the exact number). There were only a handful of Challengers (similar in qty.) to the Cuda made with the option in 72 and possibly fewer.

It wasn't until 1973 that a cheaper sunroof was offered in manual form for B-bodies only. I think 72 A-bodies also had a manual sunroof available. After 1972 Challengers and Cudas were not offered with this option.

There were C-bodies made with the M51 sunroof option also. I know there were some made in 1971 and possibly 70. The 1971 Chrysler/Plymouth general line sales brochure has more than one shot of power sunroofs in it.

Why weren't more years of Cudas offered with the M51 option? It was up to Plymouth to decide which of their models would get the option. You will have to ask them!

I do know that there were 27 Challenger R/Ts made with the option in 1971 and about 23 of the JH23 hardtop models. In 1970 there were 82 Chall. R/Ts made with it and over 100 JH23 models. You can find production in Govier's production booklet.

Why do I know something about these sunroof equipped cars? I have some experience with them.
