I spun a rod on my 96 3.8. First, how hard would it be to replace, and second, is there a place where I can find them so I can do the replacing?

 

honestly something to consider is buying a used motor...

check out www.tacreationsusa.com I think you coudl buy a low mileage used motor for cheaper then fixing yours. Also check the v6 boards, seen them go as cheap as $400 before.

 

Or buy a short block with a warranty.....
