The $70 was the most I've paid, it's usually around $60 when I'm running it dry.
I got the hitch from, uh, er, ahhh, a place on Dixie Rd, south of the 401... Uh.... Oh, thank yellowpages.ca, it's Hitch City. Cost me a couple of hundred. I think 180 plus tax, if I recall correctly, but that was over two years ago.
There's a procedure they give, where you have to drop the muffler, but I found that I could slide it in, over the exhaust tips, with some slight bending of the plastic bumper. Not much. Others have not been able to do it, so no guarantees.
One thing I'd suggest. Paint it befor you put it on. The paint that comes on it, could be better. Sort of like those $150 Bar B Q's, they rust out in two years if you don't paint them, and 6 years if you do.
The Nissan hitch is a different bumper. They have to take out your old one and put in the new one.
