"How do you attatch the shields to the heat exchanger?"

Gravity...really. They just sit on top of the heat exchangers. I bent the aluminum shield so it would sort of wrap around the heat exchanger and allow oil to run off the sides. The expensive heat resistant fabric shield is just draped over the heat exchanger. And I (sort of) sealed the slits on both shields using high temp tape. The slits are there just for installation. If you do this mod with the engine out of the car, then you probably would not need to use the slits at all. Oddly, I didn't have to do any major sealing around the three exhaust pipes. I expected oil to drip down the pipes and onto the heat exhangers. And so I expected I'd have to find a solution to that problem. But in my case, the shields worked without additional mods. Of course, as always, your mileage may vary depending on how/where your engine is leaking.
