So I have a question. I was about to start on my part F-01435A from page 28-11 Rev.2 when I noticed that on the Rev.1 drawing the part looks totally different. The part that I actually have looks like the one on the Rev.1 drawing. The part on the Rev.2 drawing has the extra cut out. Should I contact Van's and have them send me the Revised F-01435A Rev.2 part?
