i googled a few 68 cutlass an 442 pics,did some cars have doors and windows like the 1970-72.my 68 cutlass has the support bar.

 

What do you mean doors like the 70-72?
There are a few models.. 2dr post, and 2dr hard top.
The hard top model had no "support bar" as you call it.. (the "b" pillar)
and the post model (or 2dr sedan as some call it) had them.

this was avaliable since long before 70-72.. it was even there in the 50's..
A post - 2dr sedan and a 2dr hard top..

So for your questions.. there are 68 2dr post and there are 68 2dr hardtop..

 

... And it looks as though the tiny picture in your .sig file shows a red Cutlass hardtop in the foreground and a red Cutlass coupe in the background - if those are your cars, then you have one of each type.

Thanks guys I think that's the only thing I don't like about the car.it looks funny alittle to me when the windows are down lol so there going to have to stay up

 

Just to clarify, ALL 1964-72 Cutlii were available in both Holiday Coupe (hardtop) and Sport Coupe or Club Coupe (post car) versions. Note that the 1968 cars used vent windows on the Holiday coupes, but the 69-72 cars did not (vent windows were only used on the Sport Coupes in those years). It IS possible to put 69 doors on a 68 (the roof rail weatherstrip is different). Alternately, some people have put a 68 front end on a 69.
