Torn driveshaft boot

What's the technical term for this and can I get a replacement?

JNZ - OEM Lobro Joint Boot kit

 

That place sure has a lot of goodies for us!

70 for that
80x2 for the carriers
40x3 for the yolks
50 for the delrin bushings

Total: 400

DSS shaft: 750

Hmmm, tempting.

Is there anything else I am missing between the two? Are there more pieces to rebuilding the stock shaft? Or anything else that will go well with the DSS shaft?
