I personally own a 1970 chevelle 4 door with no post and I was interested in finding out if you can turn this car into a 2 door.

A 4 door Sport Sedan is a desirable car for many. The 4 door has a different roofline and is longer than a 2 door. You might want to sell the 4 door and look for a 2 door, would probably be cheaper and easier.

Yep, the 4 doors have different frames (longer wheel base, I believe by 4 inches) than the 2 doors. That alone is a big effort to change.

A good 4 door is a great vehicle.

I would agree you would be better off in the long run of selling and doing a 2dr.

Among others like the angle of the windshield and rear window. Floor pan and rockers are longer as well.

If were going that route. Then i would go all the way and turn it into a two door convertible. It can be done but wow a lot of work.

Buy a 71 or 72 hull two door use your guts and front clip and call it done
Unless the car has a great deal of sentimental value to it?

do you think just by buying the rear quarter panels and the coupe doors this can be done. im sure with some more work to it. to turn it into a convertible? or keep it 4 door and chop the roof off?

why would you want to butcher a 4 door sport sedan to do either?
There were only 20,575 sport sedans made in 1970, there were almost 290,000 2 doors. The 4 door is much rarer and having a 72 version of it I would be disappointed to hear or see one butchered like that. If you don't like the 4 doors sell it to someone that does and find another vehicle to butcher.

No because the skeleton is different too. The quarters are just outer skins. It will never look right either. If you want a 2 door that bad, sell the 4 door and buy a 2 door.

What everyone says is true. It is simply too much work and not practical to try this. An interesting twist on a sport sedan would be to suicide the rear doors. I don't think anyone has done that before. I have thought of doing it with my 70 sport sedan.
