You can still get the Silent 90ST and Top Star SE kits from MK. Replacement canopies and cowlings for most old kits too. Not sure about belly pans as they are not currently listed. You can also get their retracts and parts for them. Their latest product listing is dated a couple of years ago but is many, many pages long. We are importing and have MK hardware in stock now and will add more later with the plan to stock some "classic" items like retracts etc. MK is still very much in business.
