T-9 cover wanted

[papak]

I'm looking for a serviceable top cover for a Ford T-9. I keep getting a fine mist on mine through the vent hole in the cover. I want to try welding a bung in it's place to add a vent line. I just want to minimize my downtime as well as not having to order one from England.

 

NOTE: I have a plug welded into the right front corner for dipstick/fill access. I swapped in a ⅜" hard line with a breather on it. Due to the mystique of fluid dynamics when underway, there apparently is a steady stream of lube aimed at that corner. I lost about ⅓ liter in an hour's driving! I spent yesterday cleaning up the mess and re-installing the plug.
