Superior Super 88 kit

Now that Superior is out of business, any ideas on where to go for something like this? Actually, I have one but need some parts. I've been told for seals and axle bearings I can use a Set20 kit and those will work. Wondering if anyone has a list of the seal/bearing/retaining ring part numbers for this. Also, if there is a specific type of seal (good) to use that would be helpful. I may have an issue as my seals seem to fail on a fairly regular basis and I was hoping to track this down with Superior. Whoops.
