Ignition: Spark modifier

[Daytona]

Would anybody know where to buy a spark modifier . I have a 61 lark 259 v8. the diaphrapm is shot. Or a diaphram I can rebuild. Tom

The 61s'used the Delco window type distributor....any pre -76 GM product will work (v8)

If i remember correctly, the NAPA part number for the vacuum advance is VC685, it's the part for a mid 60's Chevy 283 distributor. You can also use a Crane adjustable advance unit which is available from suppliers such as Summit racing or Jegs. Bud
