I assume you made a few, looks good.
I made 3 sets (and of course i now have patterns).
What do these look like installed? Is there space between the two for the exhaust tube to pass? Never seen any originals installed. Are these custom or original-design Roof.?
Yes there is room for the exhaust tube to pass between. These are original design. It appears that Roof only put lettering on one and the other was plain.
