Drop spindles and disc brakes

[leadfootalan]

I have a 70 bird with disc on front. I was needing info if the kit from classic performance products for 2'' drop spindles and disc brake kit for a camaro 70-78 work on my front end with out any problems. Car has 15'' aftermarket wheels billet alum. My car is the early 70 edition and have found some parts to be 69. Please help and get technical if needed. This is the only place I can find that carries the drop spindles without cutting springs or putting in lowering springs.
