Adding a window/inspection hole in Quicktime or similar scattershield.
Quicktime bellhousings are junk compared to the older
Lakewood models. My RM-6073 is on the scrap pile. Anyone see the pictures of the gasser with the flywheel through the cowl? That's your Quicktime when it fails. They are flimsy IMO.
That said, I have 3 SFI certed bells ( 2 LW, 1 Browell) that have inspection windows. I will get you more specifics later today.
