Default Perimeter to Centerbolt - need clarification

Ok so I have a 98z. I am swapping in a crate ls6 longblock and would like some clarification on what parts are needed to get my coils to swap to the new centerbolt design. I've searched part numbers on here, I just want to make sure I get everything I need to swap it all over.

If I understand it correctly, I will need:

LS1 coil bracket (01-02) = 12563288 [2 total]
LS1 coil stud (4 on RH, 5 on LH) (HFH, m6x1x40, special hd) = 12557539 [so 9 total]?

Will my harness and coil bolts [the ones holding the coils to the perimeter valve covers] bolt up to the new brackets and valve covers? Or do I need new coil mounting bolts and a new harness?

Let me know what you guys think. Hopefully I'll get some feedback from someone who has done this swap. Thanks all!

Have't done this, but they take the same coil either way, so the connectors will work.

yes everything looks correct.. I just used flange head bolts from the hardware store (well i had them already ) but thats the same

the harness is fine

and you only need to buy the brackets
