In case you don't know, if you
buy a new top boot from Moss or someone else, the Tenax fasteners come in a
separate bag with no holes in the boot for them. You're expected
to do this yourself... I'm guessing because there's a lot of variation from car to car in
Attaching the snaps and Tenax fasteners was kind of a pain, but not too bad. I started with the two in the rear - I measured the distance between the studs on the car, subtracted about 1/4" (for stretching), and then using the seam on the top boot as a center locator, measured over and cut the holes.
For vertical positioning, I just kind of guessed... put them close to the bottom of the boot, but up about 1/4" from the bottom seam.
stretching into position, I went around the car one at a time, marked, cut and installed each Tenax, putting the boot back on the car after each in order to mark the next one.
To cut the holes, I was just using an Exacto knife and cutting a hole I traced using the bottom half of the Tenax fastener, which I just located centered over the dot I was putting on the boot with a permanent marker as I fit it on the car.
For the 3 buttons on the inside - I did these last, so there was really nothing too them - marked the locations over the existing snap on the car, pocked a hole, installed the snap, and used a snap installation tool I got from Moss (386-980).
If anyone has any questions about any of this, feel free to send me an email!
