Hello,
My dad has decided not go this route and is selling his new in box MSD 6A ignition controller and 8546 Pro-Billet distributor. The distributor fits the RB and Hemi blocks and its small diameter housing allows the distributor to fit tight block and head combinations. 6A is priced at $175 and the distributor is $275 or will sell as a combo for $400. Parts are located outside of Oklahoma City or I can ship them to you at actual cost, packaged up nice and neat. PM me or shoot me an email at wsup _ doc @ hotmail.c0m.
