Based on what I have read on the internet--you know how that goes--the replacment is too tall. Based on my experaince with rubber parts, they are too large or too small.
Mine origional broke all to chit when I pulled the cowl. It was an ongoing, weeklong project, glueing this part, let it set overnight, glue that part, let it sit, until I fixed it.
I'm usually unhappy with the results. When I'm doing my photo shoot, I try to remember to take pictures of it because it came out beautiful, with one spot appearing as a small crack.
