Roughly $100 of the cost was the green bearings and installing them.

Since one of the original bearing felt rough when spinning the axles needed bearings.

Originally he was talking $150 to drill the axles to change the bolt pattern to 4.5 but he wanted to use Chevy studs because the use a smaller knurled diameter.

I wanted 1/2 inch studs, so that meant screw in studs to keep the diameter smaller.

I wanted the ability to go back to the original 4 inch bolt pattern in the future because at some point the car will be restored since it's a factory 383 car.
