There were two different ones, from two different sellers. Both had the same crappy threads on the top back threads. Both blew out seals within 1,000 miles and spilled brake fluid from the brake light switch. There shouldn't be any liquid in there, and when you press the pedal, it flies out. Don't buy this crap. Getting one from the junkyard is your only bet for OEM. If not, you'll want to replace it and new lines with a Jeggs combo valve or something.
