The Super Tricks have a square "o" ring around the inside. but it'll probably be dried out and shrink when you take it out.
Try using a high strength sealer adheasive, not just any old silicone , an seal around the o-ring not on it . .......Mopar differential cover sealant works very well. ....Be sure to use a very small amount of antiseize on the bolt shank to prevent reaction between the steel and aluminum.
I used to make racing money polishing Super Tricks way back, make sure that you take a good look at all the holes and the inside of the bead for cracks ,since the newest wheels are still going to be at least 30 years old !
Next to Motorwheel Flys ,Tricks are still one of the best looking racing wheels out there.
