I have run Lakewood shields since the late 70's. No big deal. 143t flywheel bolts up direct. 130t flywheel, you need an adapter for the lower hole. I've used nothing more than 2 bolts and a piece of flat stock to make my own adapter. I've used a chopped off piece of 4 speed cluster shaft bearing spacer for the centering cone, with a flat washer and nut welded on the end, and then hand file the starter nose to fit.
You guys need to get a grasp on fabricating for performance/racing. If you millennials want stuff to fit off the shelf, buy a Chevy.
