..What Josiah said ~ Big A auto parts and others sell rebuilts very affordably (under $50.00) DO NOT turn in your old dizzy untill the job is finished to your satisfaction ! .

MT sometimes has NOS ones , I lucked out and found a NOS 235 dizzy in the Delco box on E-pay for $50.00 delivered . 216 & 235 dizzy's are interchangeable per GM .

Don't pass by that old filthy greasy one on the $1.00 junk box at the swap meet either ~ often it was a takeout 35 years ago and is actually in VGC once you clean it up .

There is no problem so difficult it cannot be overcome by generous application of brute force & ignorance
