Okay so I've been looking for some time for an hf transmission. After cancelling my order with JDM Source ($300 is wayyyy too much with shipping)
I decided that I can probably find one for alot cheaper then that and save some money towards my swap. I live in SoCal and am willing to drive or pay for shipping if necessary.
Check out www.car-part.com. It is a list of junkyards across the USA and shows their inventory. I just bought one from Ten Acres junkyard in Houston, TX for $300 w/shipping. Just make sure you ask whomever you decide to buy from if they can put their hands on it before you purchase it. I went through three different places with charging me for it and then having to refund my credit card because they didn't have it after all. Good luck because I went through three weeks of searching before I found mine. That website was a lot of help because they're all on one page.
If anyone is still looking for one I know one of the Honda-Tech Sponsors has a spare one he's selling for $120 in the Baltimore area. Since he's in the "Racing Biz" he might easily be able to ship it too.
