Need help making a decision.

I have a 96 Crown Vic PI and just found out that it'll cost $2100 to replace the front frame section due to it being rusted away. The engine has 72,000 miles and I just had the transmission rebuilt two months ago. I would really hate to see that go to waste so I'm thinking I could try taking them out and putting them in another vehicle.

Could anyone give me a starting point for this so I can educate myself and maybe a place I can search to find a car with no motor/trans so I can use what I have? Thanks in advance.

If I were you I wouldn't want to let that motor and tranny go to waste either, try looking for another car on craigslist.org and other auto classifieds for a crown vic or the mercury version, more than likely your going to find more cars with motors already than ones without, but may find one with high mileage or something that'd be worth replacing, if you try and go for around the same year then it will be moreless just bolting the motor and tranny in place and just plug wires.
