Interested in buying a 70 Roadrunner. Some of the cars I am finding are coupe(post) cars. Just curious if I can change one to a hardtop car with just parts. Not real sure if something is structurally different or not. Thanks.

Why not make it a post RR clone?
More desirable in my opinion.
And since you asked, I have to say NO, you can't make a post into a hardtop unless you're a top notch fabricator/bodyman. It's not simply a SawzAll at the post.

No reson to do it . If you want a 23 , buy a 23. No need to "convert" a 21 to a 23. You would have to remove the B pillar , etc, it would be a major job, then you would end up with a car that you could never sell in the future because potential buyers would wonder why the VIN says RM21 , but no B pillar to be found. It would be assumed that the car was a rebody , because most people feel that nobody in their right mind would go through the trouble of converting a post car to a hardtop. Their are plenty of both to choose from ,
and no advantage or value diffrence from one to the other.

My good friend just made a hardtop 68'B-body into a post and it was ruthless work. I'm sure the reverse would be just as crazy.
Buy a 23 and be done with it.

If you have all the donor parts from the hardtop, it's a bolt in affair, the post is merely spot welded in place, the side glass from any 69-70 B-Body HARDTOP, including the Charger will interchange, the 68 B Body side glass has a much more narrow runner on the glass tracks, so avoid 68 componets, I recently converted a customers 69 post Coronet using 70 Charger regulators and side glass, including the vent window frames, you'll need to cut a "clearance" slot for the rear qtr windows to roll down in the upper door jamb on the post car, which is covered with the rear qtr window jamb gasket from the hardtop donor, simple surgery,....actually much easier to convert a post to hardtop, than visa/versa,...besides the hardtop IMHO is much more visually pleaseing on the eyes than a post model

its not like its imposible to fine a hardtop.. coupes look awsome anyway, and even a few pounds lighter

Foe gedda bowdit. Better structure w/post.

Thank you Dayclona. That is exactly what I wanted to know. I've seen some good deals on coupe cars, but I really want a hardtop because of a car I had a few years ago. I do have a couple of hardtop parts cars. Thank you for your help!!

Do it. It makes my post car even more rare by everyone screwing them up and trying to make them into something they are not. Love it!

Maybe O/T...maybe not?

I was actually considering converting my 1968 Charger over to a post. I think it would look great. Sure, it's a lot of work.

I was also considering a Charger 500 rear glass and trunklid to go with the post. Think: large chrome 500 A pillar covers, and large chrome B pillar covers - together. Cool.

Also, I was thinking about the 1966 Charger trunkwell for the spare, and the fold-down rear seats to go with it, removing the package tray for an open area.

Anybody done this?
