I could have given you mine, it went in the recycle bin. I pulled that off of my V6 and put on the factory V8 hitch. Found mine at a wrecking yard. They are hard to find, but I wouldn't hesitate to go aftermarket - frame mounted hitch.
I did just this on my 2007. I don't think the 2004 should be different. You may have difficulty putting your hands on an original Toyota 4runner v8 hitch, and might want to consider an aftermarket one.
I have a 2007 V6 that I wanted to upgrade to the v8 hitch. I was lucky enough to find a (front end) wrecked v8 locally and did a direct swap. The hitch height/location is covered by the factory "fill plate". I don't know what to call that plate, but I think it results in a lower hitch. When...

Oh...
Shop around for HG replacement costs, and then go back to your trusted mechanic for a reality check. Hopefully, you can get a better deal from your mechanic. If not, you may have found a new pool of shops to visit.
