I would probably get on the 'net and order one of these right away. They have a heat shield on the plastic UIM which protects it from damage, in addition to a reduced stovepipe if it hasn't been replaced yet. I see you're in Canada. The guy at ineedparts is very reasonable about shipping to Canada, kind of a rarity in this world.

At least you have the LIM gasket done, so the UIM shouldn't take too long. Cleaning all those LIM gasket surfaces was sure a pain!
If you can, get a thread chaser to clean the UIM bolt threads. That way you will know the torque will be accurate.
Good luck!
