One man's correct angle could be different to another's Terry. When we fitted JV2, Ad and I mocked it up in scrap wood first. Everything from seating, galley cabinets and dash. Size, height and angle of dash were important to get right. Anyone who can do a bit of glassing/mould making could make a "box" cut at an angle, correct size and shape etc is the challenge. Shame you didn't buy her earlier, could have had 9momths to tinker at home and learn from YouTube! Good luck. R
