Quarter tonneau dimensions

I'd like to craft a small tonneau out of the vinyl I am using to restore the interior. Can someone provide the rough dimensions?
thank you.

The best way is to make a template off your car. Variables are things like , back seats, roll bars etc.

I agree Joe. I'm just trying to get the general width of a typical one.
thanks

Base it off your convertible top for the width.

I don't have a convertible top. Someone "borrowed" it. Actually I need the depth dimension - how far out over the back seat does a typical one go? I have a full tonneau but am looking to create a smaller one.

I should have said the depth dimension.
thanks

You don't want the cover to touch the front seats at all. And you'll want two straps to go from the leading edge of the cover to the rear seat ledge. That will prevent the cover front flapping around. Take the cover you haveand snap the back half in place with the front seats in the far back position. Use some chauk to draw your pattern. I'll post a picture of my cover.

Joe: does the inside edge go straight across or follow the curve of the back?

Here are a few pictures to get an idea.

Hey Joe!

Are those tools in the background the ones you used to fabricate your cool-looking cover? If they are, then DAMN you are GOOD!!

That custom cover of yours is a nice detail to an already awesome car!!

Thanks Jim ! Now you know some of my hidden secrets. You should see what I stuff the seats with.
