Quality of the boot was great. Fitment was an issue, as my 1983 911SC had all snaps (a very early build) and the boot came with a combo of Tenax and snap fasteners. When calling GAHH, there seemed to be confusion as to what to do next. They promised to call me back, but did not, even after I called again and left a message. I decided to convert my car fasteners to Tenax to accommodate the boot which was a very tight fit requiring a lot of adjustment and massaging. Overall, I am satisfied, but think that the boot could have a slightly more generous fitting.
