Early distributor on Late engine

[Figment]

Is there any reason why I couldn't use the distributor from an early-model engine on a late-model engine?

On casual inspection the gearing doesn't look different.

Thanks,

Early ignition on Late model? or vice versa

I have the opposite question. Having had a late model engine that rusted out after a rebuild, I "found" an "early" in a friend who was moving south's garage. The distributor cap was missing and the interior was solidly rusted to crumbs. I have a delco distributor from my 1969 A4 that is clean, and worked. Has anyone got a clue if, after changing the clamp, the late will work, or if not, where I can find a replacement Plate for the "Early" since the original was rusted away?

They are interchangeable however the hold down brackets are not. If you also have an early model aux drive swap out both.Installing Delco on early model block you must drill and tap a new hole.

If it would be of any help I would be willing to trade this late model dist for an early model. One of the dist cap screws is missing and one of the hold down screws is stripped. It has a new cond, rotor, points and cap. Dan S/V Marian Claire

Thanks,

the gearing is the same and it is ok to use prestolite on late models remember to set dwell 38 degrees

distributor options

While looking thru the Moyer calalogue I noticed that a distributor called "Petronix" is offered in addition to the change over kit for the Delco. I was wondering if anyone has used the Petronix distributor, and if so has it any advantages over the change kit?
