I've had it with t-tops

I went to a body shop who specializes in custom work. I requested a quote on a conversion from a t-top to a HARD-TOP. The bodyman had never had such a request before. Anyone out there either heard of it, tried it or contemplating it ?

It can't be all that difficult (although the bodyshop guy sure groaned over the idea). Find a hardtop and weld it in ? Ok, I'm not a body guy so what do I know.

Any ideas ? Comments ?

Thx, RP.

Yeah really? If they leak a little they can be adjusted.

My t-roofs are pretty good actually. I have the Lexan type that weigh in at about 3 lbs apiece. They are darker and cut out more light too which works for me....

I was considering a hard-top because the car creaks so much. It doesn't leak by the way -- it used to but I tracked these down and using my trusty black gasket goop fixed the 'holes'.

This is my third 3rd gen car and I swore I would never get a t-roof car again because the body moves so much. Especially after you add power, look out the windshield may come loose, b-panels crease, and the dash creaks... especially after I dial up my KYBs.

So I figured I would either a) get a good set of sub-frames or b) have a hard-top welded in.

Your thoughts ?

Well I'm glad you brought up the sub-frames. I was looking at a set from Edelbrock, then another set from Jamex, yet another from Global West. I have no idea what is the best brand for these cars ? Have any of you guys installed sub-frames connectors ? Did they make the t-tops and dash stop creaking ?

thx.

Yeah dude, SFCs are the way to go. You'll pay thousands to get your car converted to a hardtop, and it still won't be as strong as an original hard top. SFCs will make a much bigger difference.

RP, go with SFC's.

To convert a top, i've replaced a t-top roof on a car that got flattened by a tree, you need to esentially take the car apart.
windshield out
Interior out
doors off
hood off
fenders off
dash out
hatch off

The only way to do it is have a used roof that was cut off correctly.

This is to do it right. At the factory seams/welds. I'm sure a hard top could be welded on over your t-top roof, but it would do nothing for stuctural srength, and quite pointless.

Hard tops without SFC's creek a lot too, but corner better than t-top cars. SFC's are pretty much mandatory with cars our age, but especially t-top cars. SFC's will cure a lot of understeer. It will feel like a new car.

I was going to go with south side Machine SFC's until I saw the spohn version of them. They make a lot more sense because they are built in a t-shape. They connect to the center of the car too. That means more stability.

Another reason for creaks, and groans from your body. Is, believe it or not! Loose door hinges. Once the doors of Third gen F body cars are closed. They become a significant body stiffener. If you don't believe it. Drive your car slowly over a speed bump with both doors open. After I did my hinges. Much of the body noise stopped. Also my T tops stopped leaking when parked.
