chrysler 3 speed manual dodge rv 360 Swap

That looks like a transmission in an A body....Dart, Duster, Demon, Dart Sport. Is this video from your car? If so, the 3B383762 should probably be the last 8 digits of the VIN tag on your dash. If your Duster is a V8 car, and the transmission in the video above is yours....you don't need to buy a bellhousing, cause you already have one that will fit either a 360 LA, or a 5.9 Magnum. If your Duster is a slant 6, then you will need to find a bellhousing. Decide which motor you are going to build before you buy a flywheel from Brewers. An LA 360 and a 5.9 Magnum are balanced differently, even though both are externally balanced. Hope this helps some. :)
