heater delete general questions

Ok cool, this answers some questions, but gives ne some more questions.

First. Does anybody have the firewall delete plate? How thick is the steel it was made of? Where the heater core tubes come out, was that a metal rectangle, or did they just use 2 caplugs over the holes?

Did a regular heater box firewall pad get used, or was there a special smooth firewall pad used?

Does anybody here have those little dashboard delete cover plates as shown by autoxcuda on ebay, that they can hook me up with length and width and thickness dimensions of these pieces, so i make my own copies of these.

As far as the R/H fresh air vent goes, i may try to find a broken up heater box and cut off the end with the seal and door, and just fiberglass in the missing piece to make my own R/H vent.

Thanks
Matt
