I'm currently in the process of doing a complete rebuild on a 25 year old 4, engine airframe and also converting it to a fastback. Over the years I've used and seen many ways to attach the baffle material to the engine baffles, an rivets, soft rivets, screws and nuts, pop rivets and more. I don't care for most of these options but have had success with softened AN rivets with a aluminum strip inside. The photos attached show how I've done this 4. some of you may like it some may not, just posting for your info, also I looked a bit for past info on this and didn't find much if I'm just rehashing past stuff here just ignore.
