Shaker hood vendor diffetences

I've called both shakerhood.com and the Tommychryco and all I get is answering machines. Are these two vendors selling the same exact product from the same manufacturer? How is the quality between the two if they are different at all. Tommychryco is $50 cheaper. I need a 440 base and I've got an OEM 383 base. The hood won't close.

Try Six pack performance in New Mexico, #505-345-8539 , got my complete shaker set up from them. Charlie.
