You all seen this? Trans tunnel from uscartool

But that's $189 for a 4 X 8 sheet right?
I get a half sheet of .019 cheaper 70.00
Full sheet qould still be cheaper, then again...id probably go and cut a tunnel out of something else in the wrecking yard with battery pack sawsaw.
Cut and widen/open the center and add a strip in, then cut near the tail ,bulge, and fill.

My time is cheaper than paying someone else in cases like these.
