The drivers side 383 mount was used for the 440 but was bent out and angle iron was welded to it then drilled for the bolts that were used to connect it to the oil pump pads that were drilled and tapped. Our own Dan (berdboy) with the six pack Fury's had reproduced them years ago and I believe he sold out on them. I have one for my 68 GSS and his repro was spot on! Anyone could make one with a 383 mount and a pattern. I found a homemade one on a 383 4-speed car years ago but they did not bend the 383 mount, just figured out how to weld on the angle iron.
