Hi- we just installed a VC Vigilant from the '70s. The door gasket needed replacing, so we replaced it with a 3/8 inch rope 'Grapho-Glas' gasket, and now we can't get the doors to close all the way- the rope on the hinge sides binds, so when we close the latch, there's still a big gap at the top of the doors. Can anyone help? We're complete neophytes to this woodstove thing, but hope to save a bundle after freezing all last winter and still spending $4000 on oil!! Thanks
