this may be a bit silly, but i was just under the impression that 70 cutlasses all had the same body style as mine, but reading the forums and viewing pic, im noticeing at least 2 different bodys. which are which???

 

There were eight different Cutlass body styles in 1970 (I'm not counting model variations like Cutlass and 442, but physical sheet metal differences).

Body code:

35 Cutlass Cruiser wagon (flattop)
55/65 Vista Cruiser wagon (2 seat and 3 seat versions)
39 Holiday sedan (4dr HT)
69 Town sedan (4dr post sedan)
57 Holiday coupe (Supreme notchback)
67 Convertible
77 Sport coupe (fastback with post)
87 Holiday coupe (fastback hardtop)
