What? No partridge in a pear tree?
Geez, seems like you've got a LOT on your plate.
As for insulation, yes I plan on using some. There is quite a bit of space between the underside of the roof and the top of the pre-formed fiberglass headliner. After de-rusting and using some thing like POR-15 or No-Rust, etc. I plan on using one of the quilted Peel n' Stick type thin insulation blankets. But I still plan to fill up the space with fiberglass batting of some type as well. Don't want to bake my noggin anymore than I already have!
