Can it be done. I know where a magnum is with T's. I would like to install them in my 300 if it can be done without changing the entire roof. I know on some GM's They just make two cuts straight across and the T's were in a premade frame that just fell in and fastened down. They had know T Bar in the middle of the roof it was in the T Top frame
itself.


Thanks, Brian
 
You call yourself MRMOPAR and ask about TTOPS!? Just sell the poor Mopar and buy a damn Cheby. God damn.

May your next TTOP leak. Profusely.

Lol sorry, I had a few bourbons in me. But seriously?
 
What about the rest of us that like T-tops? Should we buy a chevy as well? :icon_axe: :headbang:

I suppose you could buy a Pontiac instead. :bootyshake:
 
Thanks for the response! That was the info I was looking for. I figured the people on this site would be glad Im
saving the 300 from the crusher. I would like it to have the options I want.


Roof has framing in it for the T-tops, so I swapped the whole roof on one of my Mopars. Good luck!
 
I've seen Cordoba's with T-tops. Were they an option on the 300? If not, why not? Would be cool to have a 300 with T-tops.

I have a few 1978-79 Magnums with T-tops and one 1979 Chrysler 300 with them, code M55!

Yeesh, I guess anyone who wants a V8 should buy a GM aswell eh? lol ;) kidding of course


Always wanted t-tops for the doba
 
Sure it can be done. We used to put sunroofs in all the time when I worked for Toyota. I know a T Top is much more than a sunroof, but you can do it. It's certainly not something for a novice. Also FWIW, Chrysler never cut any roof on any car be it sunroof or T Top from the factory. They were sent out and the work was subletted to another company. They were all aftermarket.
 
I might have to disagree with that last statement.

I'm pretty sure the sunroofs were factory, but the parts may have been outsourced.

The hole in the roof panel is stamped, and the edges rolled.

Is the aftermarket capable of doing that?

I got a really long artical on the actual companies involved somewhere...it came from this site...

I have seen an E body Barracuda with retrofitted T tops, and it was sweet.

I thought about trying to adapt Magnum/Cordoba T tops to one of my 73/74 cars.

Chrysler was just late with those, as it was with many styling trends.

Just thiankful that the engineering was "ahead".

A few? Brother, I think you have the market cornered on Magnum GT's and XE's. I really liked the black GT you had for sale a while back. I just wish it had buckets and a console. :headbang:

if you have a donor car you could do it, dont try to use a gm peice, they were specific to the vehicle. i'll run ya down the basic process. there were several aftermarket t-top manufactures...hurst, Cars and concepts and american, if i am not mistaken the t-tops in chrysler products were made by american or hurst. miradas,cordobas, 300's had been retrofitted with them. sunroofs were the same way for chrysler, they never made thier own. if i am not mistaken some sunroofs were put on during production others were sent to an off site vendor to be done. chrysler still coded the cars for the option , if they were order specifically for it even if they were installed by the outside vendor. progam much like the hemi superstock cars that went to hurst. you would need to make a template out of the car you are taking them out of, take the headliner out to see if any cross bars were cut, modified or moved. in a nutshell, the cars would come into the shop,gaskets would be stripped of the door frame opening, the gasket channels were removed and set aside, headliner was removed...there was something called spreader bars put in the door opening that had a turn buckle in to support the vehcile so it wouldnt collapse during installation, this was used more in GM f-bodies when the entire center was cut out, the templates were put on the roof and measured based on a distance from the windshield.tape up the roof so the tools dont do paint damage. depending on what type of cutting equipment was used, some installers would use a sawsall to get through the heavy roof channel area and switch to a saber saw once they reached the sheet metal, if you should tackle this, let the saw do the job, dont force the cut. once the cuts were made they would file the raw edge sand prefit the frame,make sure the frame has a little bit of play, if it is hard against the sheetmetal opening when you screw it together it will warp the sheetmetal, there should be an inner and outer frame, screw them in place and prefit the glasses. once you have determined you are ready to put it together, get a tube of adheasive/sealer caulk, pullup your tape, lay a heavy bead of caulk around the opening,slide in the frames, screww them together, install the glass for a second to check to make sure the frame didnt trist or warp, pull it out, use a bondo scraper to take off the excess caulk and use a liberally wet rag with preclean on it and clean away... the rest i am sure you can figure out on your own, you said you have a car to use as reference, study the crap out of it. if you should decide to do this.... good luck! i have done a couple hundred t-tops over the years, they havent made kits since the early 90's and nothing for cars of any real vintage. take pictures and post them if you should do it.

WOW that was a helluva write up!!
 
That's the article I was talking about Rusty, but it kinda skips over the 69-79 Mopars.

BTW my 86 Daytona T top was a C&C job. I definately remember their plate in the door jamb.

Also- I've noticed a hell of a lot more 1974 B body cars with sunroofs than any other year.

Me too! I Do have plans to do just that. The main reason for this Magnum is that it was a low mileage 79 Black E58 package GT with T-tops :)
1979 E58's had 20 horsepower more and 20 torq more that the 1978 E58's
