Conversion headlamps ... help!!!???

Hi, I have a 1983 oldsmobile delta 88 and I bought a pair if halogen silverstars but then I seen on car domain, a couple of people had conversion headlights on there deltas and I really dug the way they looked crystal like. I tryed contacting the few people that had the headlights but never got a response so I looked on ebay and found some that were for a regency the same year as mine but when I emailed the seller, he said they wouldnt fit?? I am not positive but I believe they will interchange, they are 4x6 and have the 3 prongs. If anyone knows where I can purchase conversion headlamps for my car or have any information on it then please feel free. Thanks
