The lightning rods are bad asss if you ask me. Having that and a custom console panel made by Mark Huffman (buickgn.com) would be the ultimate finishing touch on any gn's interior. I was looking on ebay for the 4 speed rods, auction ended at over $500 for a nice set.
if you have never worked a set off lightning rods, try it. they are actually pretty fun. i still have the original set from my 83 hurst. if my car wasn't a track car(three speed) i would try putting them in.
