Sax iyo darawalkii baabuurta isboortiga ee Dave MacDonald, oo ahaa qof ku cusub 500, ayaa ku dhintay shil baabuur oo ay ku lug lahaayeen todobo baabuur wareega labaad ee 1964 Indianapolis 500
Waxaad MacDonald waxa uu waday baabuur uu lahaa oo uu naqshadeeyay Mickey Thompson, #83 "Sears-Allstate Special". Thompson wuxuu ka codsaday saraakiisha USAC inay soo booqdaan dukaankiisa California si ay u baaraan gaariga inta uu dhismaha ku jiro si uusan lacag ugu gelin gaariga haddii ay jirto fursad ah in laga saari doono Speedway. USAC waxay aqbashay codsiga waxayna u gudbisay baabuurka xirmada saamaynta dhulka. Waqtigii uu gaariga soo gaaray Speedway bishii May, USAC waxay bedeshay fikirkooda waxayna ku guuldareysteen. Ka shaqeynta meelaha cidhiidhiga ah ee garaashka, Thompson iyo shaqaalihiisu waxay dib u dhiseen gaariga si ay ula kulmaan qeexitaannada cusub ee USAC. Isbedeladaas, ka saarida baalasha, u beddelashada taayirada waaweyn iyo kordhinta dhererka laba inches ilaa afar, ayaa gawaarida ka dhigay kuwo aan xasilooneyn. Graham Hill ayaa tijaabiyay gaariga ka hor Indy laakiin wuxuu diiday inuu kaxeeyo 1963. Masten Gregory wuxuu shil galay horaantii bishan sababo la xiriira kor u qaadista hawada. Kadib markii MacDonald uu isreebreebay iyo tartanka ka hor, Jim Clark oo ah Horyaalka Formula One ee Grand Prix World, oo yaqaanay MacDonald isla markaana ixtiraamay awoodiisa, ayaa daba socday Californian dhowr wareeg. Markii ay soo gaareen, Clark wuxuu si adag ugu booriyay MacDonald in uu baabuurka ka baxo. "Iskaga bax", ayuu yiri Clark. Ka soo bax oo iska socodsii". Laakiin MacDonald waxa uu dareemay in ay waajib ku tahay in uu fuliyo heshiiskii uu la galay Thompson. Darawalada kale waxay qaateen talada Gregory waxayna ka fogaadeen gawaarida Thompson. Ka hor tartanka, Gregory wuxuu u soo dhowaaday Jack Brabham oo ah darawalka Formula One, kaas oo ku xiga MacDonald oo ku jira shaxda, wuxuuna ku booriyay Brabham inuu u oggolaado rookie-ka qol badan. Brabham wuxuu ku amaanay talada Gregory inuu badbaadiyay noloshiisa.
