I am considering installing roller shade/screen units on my two Lewmar hatches. Lewmar carries this item as an accessory, and OceanAir also has similar units that will fit. I am interested to know if anyone has experience installing these on a 356, and if there is anything special I need to know. I think the Lewmar units come only in white, while OceanAir has both white and beige. I would prefer the beige to match the rest of the headliner, but would be OK with white if the Lewmar units are a better fit or easier install. Any advice would be appreciated.Thanks.PeteS/V "Sh'boom!"
