Spreader Sizes on Hunter 42 Passage?

[Sailingbum]

I'm needing to order some spreader boots, but Hunter sells them in sizes from 1//4" to 3/4". Before taking a hopefully unnecessary trip up the mast simply to measure the first spreader, does anyone have an idea of the size I'll need? Much Thanks!

If you know the manufacturer of your mast, you can probably call them and ask.

Our 1991 P42 came with an Isomat spar, NG-70, I think. Replaced the boots many years ago, but do not remember the size. Might find what you need here: http://rigrite.com/Spars/Isomat_Spars/ISOMAT_Main.php
