The lambo door conversion simply will not work well with a SVX. It has been done with varoius levels of success. But in the end, nobody is realy happy with it. First, the SVX doors are Realy heavy and rather oversized. This would require perty stiff struts to aid in lifting. Not to mention, swinging lambo style, its near imposssable to get the doors to swing open wide enough to get in and out of the car with ease.
Second, shape of the door and the body lines cause problems with getting the door to open and shut flush with the body. As has been said, It has been done, but its not worth it.

I hate to say it, but do a search and check the threads on this subject. You will find good pictures and decent writeup on the intall.
