Now how much was that you wanted to bet Jim????
Neil, there are a bunch of angles that you have to deal with so it would really be difficult to draw that up. I would suggest buying one of the cardboard sleeves for ten or twelve bucks and using that for a pattern. You might luck out and get one that fits the opening the two that I got were two small and wouldn’t go over the flange, other than that the rest of it would have fit behind the dash ok.
I can tell you this, I traced a cardboard template of the opening then made a wood buck from that. I just kept touching it up on the belt sander till it just fit the outside of the flange. You have to make a choice whether you want the staples on the outside or the way they were made originally, stapled from the inside. The later becomes quite difficult unless you have a stapler that will reach in about 10”. The cardboard boxes leave the flange on the sleeve back facing out and this can be stapled with any heavy-duty stapler. The only real difference is that you gain almost an inch the way the factory did it.
