Putting a 273 in Old Red Val.

I pulled the trigger and bought a used 273 with auto trans, attached for a low price. Now the fun begins. Since I am not equipped, with tools or talent, a friend in my car club owns a local speed shop, http://www.bobbycspeedconnection.com/ in Norfolk Ma..
He agreed to do the fresh up on the old 273 and engine swap. It been sitting for ten years, but preserved nicely.

While I have the car in a shop and the doing the K-frame engine swap. I decided to do the disc conversion as well. But $$$ is tight and I want to avoid going to a BBP wheels. I found this sort of bolt on option.

It at Scarebird brake conversions - http://www.bobbycspeedconnection.com/

Has anybody used these? any comments.

Also looking for a 8 cyl transmission cross member set up for dual exhaust.

Thank you
