Good luck finding one for $100, I paid $150 for mine a few years back from a local junk yard and it was one of the cheapest on
Car-Part.com--Used Auto Parts Market all of them near you are $300 to $400 and shipping is going to be pricey because I think they weigh over 50 pounds.
Your best bet might be to find a local body shop that caters to teenagers who think they are building race cars as most of them pull the vx/cx transmissions, they might even sell it to you at scrap price.
