It is not the same car. I once thought it was but the author of this thread and owner of the red Remlinger convertible said it was not.
He may be addressing this in post number 31 above. Although it was common for 71 Cutlasses to be converted to 72s courtesy of Oldsmobile's Dale Smith sending the racers grilles, headlights bezels, and taillights. That Cooper Speed Shop Al Seger convertible in my signature picture below is and example of a 71
later converted to a White 72. The chrome strip along the lower body(also on the blue Remlinger convertible) is incorrect for 72 and you will notice on the white 72 converted car below they left this 71 molding in place. It would take some bodywork to switch out the molding- filling in holes and making new holes and if the blue and red Remlinger convertible was the same car it would have been a painstaking conversion but not impossible. But per the current owner we know they are not the same car. On the red Remlinger convertible you see a thin bodyside molding that is correct for 72 and the chrome rocker panel molding along the very bottom. 70 and 71 Supremes had the wide chrome molding that you see on the black and white pictures below but in 72 they moved to a thin strip like the red Remlinger car below. Too much information Im sure.

Two cars above are same car. Cutlass SX 455 were rare cars
and convertible SXs are even more rare. Correct me if Im wrong
Ive heard this car was sold with an incorrect 350 engine installed and
the 72 changes intact? Al Seger then moved to the 72 Go Shop
Cutlass Cruiser flat top wagon in 1973 that he must have raced until
he got a white 76-77 Cutlass? and then a 78-79 98 Regency?
[quote=Hemi Moose;359493]I was just wondering, is this the same Olds convertible or a different one...

Different cars
