Our pumps are the small TC pumps used by companies like Zoops, March, and Billet. Actually we supply them with their pumps. The pulleys we use are not utilize a keyway. The pulleys require an installer to put them on, which we do before we ship them. We do offer three different pulleys, a single, double v-belt, and a serpentine belt.
When we do a rack and pinion conversion kit to a car we always do research to the most popular header used on that car. In all Mopar cases it has been TTI headers that has been the header of choice. Howerver other headers might work, but I have seen engine mounts make headers not work. I guess that's why they call it car crafting?!
