I would check with Brian. He is quite learned in these matters.

 

The major strength of a normal vehicle is mainly in the roof structure,as this keeps the whole frame from flexing.
If you notice today's cars,the strength has been moved to the front pillars...you will notice how thick and solid they are.
Convertibles NEED a boxed,heavier frame to keep it's body integrity.
Welding frame rails to your hardtop should be a no brainer...it shouldn't really matter as long as the welds are done correctly...as you still have your roof structure.

 

When you use the convert frame rails, you should also use the convert trans cross member...you might notice that the hardtop cross member is longer on the ends Vista Cruiser uses the same rails and cross member as the convert.

 

I would say "must" use the convert crossmember, not should.

Note that for 1964-67, you could actually get the boxed convert frame under a hardtop from the factory by selecting the Heavy Duty Frame option.

 

On 66-7 all body mounts go into the main frame, not the convertible boxing pieces. I am not sure about all other years, but suspect the same is the case. When adding the boxing parts, be sure they are slid over the original frame C sections the right amount, and the spacing is correct so the crossmember will bolt in, and have the transmission mount pad located correctly.

 

the big picture ,of this build will have 4 inch exhaust , so the cross member will need to be modified,and the motor is going to set back a little . this will be a gasser/drag car,.

 

sorry i think i mighta requested the wrong reply, are the braces on the body the same as a hard top ,or this their anther brace supporting this area of the body.i under stand ,i am adding strenght, that was the idea. i planned on going with a look alike art morrison , but the added weight , was killing the plan , and the convert frame rails ,was a lighter way for what i needed in this build , and plus gave me more center support.

 

Where did you find these i have been looking for a set i have a mint hardtop frame that needs to go under a convertible some day?

 

BRAIN TRICK /507 olds, HAD THESE, i believe he has frames and frame parts , good guy to deal with and easy to get along with. look him up.

 

Thanks for the info i will check him out.
