Need Spring/Brake Advice on 69 Camaro

[bbbentley]

In the process of building my 69 Camaro COPO serious drag contender replication. Here is what I am seeking opinion on:

1) if you were trying to replicate a COPO turned drag car, Stocker or Super Stock type car, what rear springs would you use? Would multileaf, as a COPO used, be the preferred look? Or, would mono, which were preferred for drag, I am told, make the correct impression? Remember: COPO clone drag car when answering.

2) Basically the same type question regarding front brakes. Would you run power disc because that is how a COPO came or standard drums because this was a modification done for drag racing.

This is not a cost issue. I already have all combinations on hand. Thanks sYc.
