Well I have a 1999 trans am t toped and I was wondering what type of mods would I have to do to make it a convertible

 

LOL, might as well buy a convertible for the amount of time and effort it would take.

 

For all intensive purposes, it's impossible. The T-top/Hardtops were designed seperately from the Convertibles, unlike most convertible cars that are converted hardtops.
But to give you an idea, if it is possible, you'd have to switch out: rear quarter panels, hatch/trunk, interior paneling, interior channeling for water runoff, an actual top frame assembely, steel framing to attatch the top to, a different windshield assembely, and weather stripping. I'm sure there's more to it than that, but the fact is you might as well be building one from scratch if you do this.

 

Would cost you enough to prolly buy another f body or two. lol

 

I heard alot of the same stuff when i was goin from hard top to t tops ... Do ur research read read read, compair the two if u can but the most important thing would be the SFC all the other stuff comes after ...

 

find some guys moving a large piece of a building across the road, drive under it, profit??

 

Profit indeed!!!

 

"Duck or you're gonna be talkin' out your ***!"

 

For all of it to be done right you would have to rear clip the car across the front floors with a convertable rear clip and across the windshield post with a convertable windshield frame. All in all gonna be money and time ahead to just buy a convertable

 

If you were closer i would trade you my convertible for yours!

 

im pretty sure to do it right you would basically have to replace your car from the front fenders back with a vert car.... its pretty impractical, vert cars being unibody are braced more underneath, plus different quarters, trunks, let alone the top structure, it would be a really expensive and labor intensive job.

 

Hmmmm well thanks for the help I will try to go the easy way out and try to sale mine and find a convertible
