You need to replace the k-member with 1 from a v8 Duster, it has the proper engine mount brackets, would also replace front drums with disc brakes if it has drum, with added power, need better braking. you can buy a conversion kit also if you cant find a k member these mounts will bolt right in to the existing k member and bolt to the v-8

Look up Schumacher motor mounts. Schumacher is a company in Seattle that sells "conversion mounts" that makes it EASY to swap that old leaning tower of power. Keep in mind that 70-72 has different mounts than 73-76 cars and 318 mounts are different than 340-360 mounts (boss on drivers side is smaller on the 340/360). The transmission mount is the same. You can find Schumacher mounts on eBay or Google them and they are excellent at making sure you get the right mounts. I just did a 340 in my 76 Duster with EASE.

Did the 1976 Plymouth duster 360 have catalytic converters on it?

NO...the '76 Duster's 360-cubic-inch engine (option code E58) was equipped with dual exhausts, an Air Injection Reactor (AIR) pump, and no catalytic converters. It was a "49 state" option, meaning that it was not offered for sale in California. Also, the 318 cubic inch V8 was available in all '76 Mopar A-Bodies (Valiant, Duster, Dart, Dart Sport) optionally with an AIR pump and a "conventional" (non-catalyst) exhaust system...again, this was a "49 state" option that was not available in California. We had one that we ordered new in '76...it looked like a "Gold Duster," but it sounded like the Bluesmobile!
