Which one to buy?

I've had my convertible for 20 years and its been down for several years while I do the resto. There is nothing like doing a 2 block burnout with the top down grabbin gears and listening to that small block scream. I have a hardtop as well and although its a nice runner an evening cruise with the top down is unmatched in my book. Going to have to V8 the dart to get the full effect but that's not hard. I've got spares of everything except a windshield.
