What are you wanting to do? HPDE days or something like SCCA Vintage Racing. HPDE doesn't require a roll cage but any racing does. Granted always safer with a cage. At least Satellite is a 72 so aftermarket is better. I would do Hotchkis TVS, largest T Bars and about as 500 hp engine for HPDE and autocross. Vintage race car clone would be cool.
