Denny's stuff is very nice and makes the whole job much easier also allows for options on the header side of things. We did mine a little different by keeping all the stock stuff which required the trimming of the passenger inner fender but not having to move the shock tower. I still have torsion bars, Z-bar for stick with Lakewood bell housing and all stock suspension parts. Denny built my K-member with motor mounts for me and we used TTi's headers, it all fits very nice although I don't have a heater in my car.
Oh I also used the flaming river small steering box in stock location and a mini starter other than that no fuss no muss. I will say make pig tails for the starter because hooking it up after the motor is in is a major pain in the .....
