340 engine mount brackets

[challenger3406pk]

I have a ser of 340 motor mount brackets on my car that I have never seen before. I've had the car since the early 90s and they were on the car when I got it. Any ideas what they are from???

Is that someone's idea for a solid motor mount maybe?

Are they like that on both sides ?  The small block drivers side if the rubber fails the motor can twist and the throttle sticks .  Maybe a solution for that .

Never seen a set with that iron shield around the rubber mount... learn something new every day.

Moparleo--- Great link! I guess they are the real deal legit! I haven't cleaned them yet to find the part numbers. In all the cars I've parted never seen em before.

73chalngr--- yes they are both like that. The car is my numbers matching 73 340 4spd car. Amazed these are still in the car.
