If there is clearance, 1/8 inch, between the headers and block, and the K frame, it will probably fit. DRE provided mine, fits like a glove around the oil pan, with Kevlar sides that go from the pan up the sides of the block, with notches for the pump and motor mounts. The Kevlar can go against the headers. I thought mine would be tough to put on, but once you figure how to secure the straps, its relatively easy. I have one strap going to a header bolt, the rest wrap around the motor mounts and one across the top of the trans. You can't really see it from the top in my 63 Plymouth Sport Fury.
