91 Eldo New Distributor


Recommended Posts

I m putting in a rebuilt (Cardone) distributor. Anybody know what size the nut is on the dist. hold-down? Metric/US thread? I am going to buy a dist. wrench and I don't trust the knowledge of the parts guys!

Don't know what size, but I am pretty sure it is metric.

Right on as usual. It is 15mm. The distributor is in and I will take it for a test ride in the morning. All I have to do is set the timing. The manual says to jumper pins A & B at the ALDL. It looks like there are not any pins in that position on my car. I am looking at the connector by the parking brake pedal. I think the location of A & B are top row left hand side in position 1 & 2. Does that sound right to you guys? I will take another look in the morning.

That era of Cadillac....the ALDL is toward the center of the dash..behind a cover..

I checked my manual and it shows the ALDL on the left side by the brake pedal. I do have a connector there but as I said the holes are empty on the first 3 holes on the plug. Could you tell me where you think the plug is in more detail? Do I have to remove any panels to see it? I looked this morning but I didn't see anything.

See this thread, Scotty posted a photo of the ALDL connector and there is info on timing the 4.9, Mike
