If that petcock is unusuable you can tap the fitting for a 1/8" pipe thread. If yours is like the two I have the petcock is externally threaded and replacements are hard to find. But a 1/8 pipe tap will thread the inside of the tank fitting so you can thread a nipple or male petcock into it.
I was looking at a couple mx 80 and 100 tanks. But I saw this RD tank for 14.95 and I couldnt pass it up. Plus I had a 76 RD 400 at one time and i really like the looks of the tanks.
