There have been other posts on this. It is extrememly difficult and expensive to do it properly. It is almost always better to start with a real convertible, according to the general consensus I have seen here.
If you have to do it, don't ruin a coupe, use a fastback.

Yes....there has been plenty of these questions asked and answered.

If you have deep pockets, loads of skill in metal fabrication and parts scrounging, patience, and complete disregard for being cost-effective...then by all means...get going on this.

Otherwise, sell your coupe and source a convertible and go from there.

 

search "coupevertible"

 

heh, heh, i kinda figured it would be this way or else there would be a crap load of coupevertibles. i was curious if instead anyone tried just making something in the middle like a removeable hardtop where it looks like a convertable without the top. yeah i know it would be a pain to remove the top to a certain degree,...but two people and space in a garage wouldn't be too bad. what do you guys think?

 

You would need a lot of additional stiffening/bracing. On a coupe the roof takes a lot of load, convertibles had beefed up/added metal to compensate for the lack of one.

But *anything* is possible with enough time and money...

 

No I mean search for the username "coupevertible". He turned a coupe to vert and IIRC he has a removable top as well.

 

As a convertible owner and one who had previously considered what you are now, I looked at the "Ronster" over at the mustangsplus website. That really isn't my style, but it gives you an idea of some of the structural reinforcements you would need. It's a lot of work. Learn to weld and buy a rusted convertible, it'll still be cheaper and faster. That site reference should help you make up your mind one way or the other.

Funny, Russ verry funny } .

 

Most cost effective way is to reinforce the belly and then just cut the roof off and cover the big hole behind the rear seat with a tonneau cover.

I visited my brother in Sacramento and this was a fairly common thing to do.

Of course if it rains.....

 

I was wondering if anyone actually read my post.

ive done it both ways,of course the best way is using convrt components which most are avail aftermarkethowever you still need from an orig convrt the area behind the rear seatand the mounting brackets by the rear int qrts and the convert top,moldings by rear and windshield moldings. the windshield frame is the same except for drilling some holes and skinning back to roof sheetmetal. wes
