I have an older renegade hybrids V8 conversion kit that I'm not going to use.
I never tried installing it, but looks like everything needed. I also have the motor mount crossbar not in the picture. I think the only other thing you would need are hoses and a motor.
A new one is $1900 without a radiator.
Sell for $900 + shipping (its heavy so probably north of $100 for shipping)
