I run msd probillet distibutor in my 74 swinger and there was approx. less than 1"room from windshield wiper motor, msd probillet is 8"tall and 5 1/8" diam. Now i take my engine off and i remove windshield wiper motor 1" inside a car because i will use DUI distributor in my next engine and i wanna be sure that it fits.
Looks like DUI is 8,5"tall and 5 1/4 diam. So it should fit.
