Bent Port Inside the Enclosure?

I building an enclosure in my spare tire well for an Infinity Perfect DVQ 10 with the mid insert.

I can get 1.75 cubic ft but my dilema involves the port length.  Infinity calls for a 12" long 3" diameter port.  If i keep the top of the enclosure flush with the floor the maximum depth i have is 10".

I would preffer to keep the enclosure flush with the floor, that bing the case can i actually have a round port in the shape of an L?

What dyohn said..many enclosures bend inside..especially with lower tuned frequencies..just get a pvc connector and turn the port..just make sure there is a good distance from the port and the sub. Let us know how the box turns out.
