Although I'm not certain what you mean by a 'shelf type, but I have one to install in my '92. The directions are for all 745/765/945/965/V90. If you find that the faxed instructions don't match your cover, I have a the 2-page directions for the other. They are quite simple, but you will need all the parts! There is a two-part bracket (2) that attaches to the rear post behind the seat and a hook (2) at the tailgate post. Three holes total on each side. Trouble is the measurements are all in metric, so you have to go to the closest drill bit that fits. I had to buy indivudal ones from Lowe's

You can best reach me at jshatzer@jhmi.edu after the holiday week-end or shatzers@earthlink.net. You'll need to give me afax number, of course. Good luck.
