Goatman,
Its been awhile since checking this post. I have a big file downstairs with Andover part #s, specs. etc. I wanted to make a decent article on the seatbelts but the camera screwed up. Since you have a hardtop, your problems are easier to solve than if you had a convertible.
Let me know if you or anyone else needs the info. Start with Andover's website:
www.andoauto.com. They have a lot of info on mounting options, specs, details and prices.
