Okay,
Here the scoop with my A66 cars:

My convertible, which I purchased in June of 1978, no buildsheet, it had the 340 4 barrel emblems on the R/T hood and 15" ralleys:

EN1
P37 R35 V5X Y05 26
C62 G34 J54 N41 N42 P31
V3W A01 A66 B51 C16 C55
FC7 H6XW 000 303 Q09711
E55 D32 JH27 H0B 269XXX


The hardtop I had in 1982 that HAD THE DECALS on the R/T hood. I have the buildsheet for it, JH23H0B227XXX, SPD of 1/06, EV2/V1X/H6X9/V9X, Y05, W21/T87 tires, J54, A04, C16, G11, G34, H51, R11, S77

I also have the buildsheet for another A66 convertible, FC7/V3X/H6X9/V98, D21!!! JH27H0B296XXX, SPD of 403, Y05/Y14, J54, J45, R11, W23/T87

Interesting, the buildsheet for the convertible lists the N65 torq. fan where the hardtop with A/C does not.

I have a letter from Chrysler stating they made 266 A66 340 convertibles in 1970.
