I have always used Mothers Chrome Polish with some steel wool. Made the aluminum slots look sort of machined finish but if you keep going can be brought to a high polish.
I'm eagerly awaiting your progress! Just looked at JVX's website and couldn't find the LA to 8sp adapters. Could you tell me what's the part number on that flex plate and any other details about it specifically?
I have no experience with either but here are some other possible options...

Look around where you live RRR. You might be able to find a shop the will make any A/C hose you need locally. Even in hot rod hell Tucson we have a shop that does that and they have been lifesavers at times when swapping in parts that weren't OEM.
