Differential cover with an Add/Drain spouts, exist?

Hello all, I have a quick question that came to mind. I am looking for an aftermarket rear differential cover with an Add & Drain spouts bolted on to the cover. Do any of these exist because it would make life so much easier doing preventative maintenance for my 1996 RS Camaro? It is a V6. I looked at Summit and one was chromed out with a single spout. Common sense would make these differential covers exist with an easy way to drain the old fluid out. Thanks for your input :confused:

Yes, they exist. Try our supporting vendors, but most of the aftermarket performance aluminum ones also have a drain hole: Mac, SLP, T/A, LPE.
