Quick question, from below, is the body tub for both coupes and convertibles the same? Thank you In advance.

 

Body tub from below?
Do you mean the frame?

 

No, I mean the underside of the body tub. In the rear section of the cockpit, convertibles have mounting spots for hardware that coupes do no not, my question is, on the underside of the body tub, are they the same?
