This cooling duct is cracked and missing a piece, but I've saved a few on Ebay since your last suggestion. I'll probably pull the trigger on one sometime in the relatively near future.
Speaking of Ebay and pulling the trigger - I couldn't help myself and pulled the trigger on one of these a couple weeks ago.
It arrived on Saturday. Now I'll have some more garage art!
Here is the front and back on my queen bed for size reference.
There are a few different styles if you're interested.
As for the dash removal from the T top car - since I've slept on it, I think the wisest path would be to just cut the driver's floor pan out. Then I can stand on solid ground and probably have more clearance to see/reach bolts and such on that side of the car. Time will tell what the passenger side reveals, but that may get the same treatment. I figure if I cut it at the front torque box all the way back to the front leaf spring mount that I'd have plenty of space. I'll leave the rockers and transmission tunnel intact as those are the structural pieces to keep the car from folding....
