Bambi vent lid about 13x13
I have a 2001 Bambi with a rear manual crank up vent lid that is just over 13x13 overall, NOT 14x14. It has of course finally shattered. I would like to replace the outer lid, the inner trim plate and screen. Are such parts available? Or is it a trip to the dealer or General RV, wait a month, and pay 400 dollars for a 20 dollar part? A "universal" 14x14 vent lid did not fit, too large, and a vent lid from Inland RV is also too large.
Any help would be appreciated.
