Hello, I am converting my 64 riviera to a 700 r4. I have ourchased the conversion kit from speed gems and all that is fine. My question is ... has anyone else done this to a Riviera with the X-frame? What procedures or other kits did they use as far as shifters, linkages, Detent cables etc... to make this work. I tried a search and have not found any significant info. I see LOKAR has several cable, cable shifters and adapters, But I am not sure exactly which ones may work. ANY help on this would be greatly appreciated.... Gone too far to turn back now! Thanks in advance!
