Thanks Mike, that would be great. I measured distance from mast step to former chainplate location (I moved them to the outside of the boat due to core damage around them and potential crevice corrosion. The distance was ~46.5 inches. Distance to new chainplates measure ~48 inches. My old spreader is about 35 inches. So that is a pretty major discrepancy! But when I look at photos of the boat when it was rigged, there is a pretty pronounced inward cant to the upper shrouds, though. Hopefully this was normal and the spreaders had not been cut down by a foot!
