Just bought a new tour-pak. Got the new hinges at the same time. They are a bit of a pain to install. You have to drill out all the rivets on the stock hinges. Made me nervous to be drilling and grinding on a brand new tour-pak. Here are the results.
The -08A part number works for all TP's from '88 up, even chopped and fiberglass, as revealed in another recent thread here. Here's the link. I may spring for these even though I rarely use the TP.
Did you use a center punch in each of the rivets before you drilled em out?
You don't need to center punch them. I did find that grinding the rivets with a Dremel worked better than a drill on the hard to reach rivets under the lid seal.
