I also use rifle drilled axles, star flange too, same rear in my 65 Impala now. I felt for the little extra wht not. Just my 2 cents.

I agree, lighter is better as long as you have a good clutch and spend the time testing. It is easier to make the car look pretty with some flywheel weight, but once you go lighter, and figure it out, it was quicker for us. The stickshift stuff is fun and way better than the 30 years ago stuff many recall.
