It looks like I've opened a subject that a lot of folks are interested in. I've gotten several comments from the Letter Men privately, as well as all the replies to the 300 forum community at large.Overall the responses seem to indicate that guys over 6 feet are less than pleased with the factory geometry, and also that the late 50s owners are not as comfortable with the factory setup as the 60s owners. I brought my drawings over to my favorite machine shop this morning of a very simple (yet effective, I hope) adapter "shim" to fit between the mounts and the seat cushion frame. It will be a bolt-in adapter requiring no drilling or bolt cutting, but there will be a fair amount of adjustability to it as well. I'm going to initially set it up for a calculated additional 1-9/16" tilt from factory as measured at the top of the seat-back. There will also be a ½" lift and a 2-1/2" rearward shift. I'll let you all know how it comes out soon. Thanks for all your very helpful comments.
