Rubber Floor Mat Installations -- questions

[Detonator]

I'm working on the installation of a Dennis Carpenter rubber floormat in my '35 five window. (Note: DC tells me they haven't made a '35-specific floor mat since 2012 when the molds "wore out") I'm using a '36 mat, which is okay -- I'm running a '39 trans and the '36 mat drops cleanly over the shift tower.


Questions:


I had to cut and fit the Carpenter insulation mat -- it's just a blank rectangle of horse hair -- should I tape it down before installing the rubber mat?


It appears the rubber mat will have to be trimmed here and there; does it go UNDER the aluminum sill plate? Or butt up to it?


I laid the matt in the sun before starting to fit it up, which helped -- but do you use a heat gun to form the matt over the transmission tunnel?


Are there clips/screws that hold the matt in place once it's been fit?


Thanks

I have heard of guys duct taping some foam rubber down on the top of the tunnelit just to fill up the gap under the mat. I had to do that on mine. On my '37 the mat just butts up to the door sills.
