i spent the day installing the TTI headers and engine front accessories. The front engine accessory came in a kit from Bouchillion and had all the bolts , pulleys, line adaptors and belt. It sure saved time looking for these parts piece by piece. The TTI header install was flawless, I will need to clearance some of the tranny crossmember and floor slightly. As you can see I have plenty of ground clearance with the header collectors.
