MOTOR MOUNTS AND BRACKETS

I have a 73 Scamp with QA1 K member set up for small block 72 Biscuit mounts and engine is a 360 magnum block with 470 HP and 500 fpt. and looking for engine brackets and mounts that are good quality and so far ether Mancini or Schumacher are not available and been searching with no results.
I am not real smart finding things on the internet so was hopping some of you could help me.
And thanks for any feed back.
