Boy what great service on Christmas day. Thanks guys for the drawings and the ski article and exactly the info I need to do a first time install appointment on Monday. Really appreciate it. Though I might be in trouble getting them so as a backup I emailed Wipaire thinking they would be closed till the first part of Jan. What a surprise in about 5 minutes Jason Erickson Director of Field Operations emails back and said he will check on Monday for me and when I came in from the shop tonight after taking the plastic off the old skis he had sent the drawings also. In my 67 years I have never seen anything quite like what happened today. Thanks all you guys and a special thanks to Jason at Wipaire.
