48 B1B Needs a distributor

[DarrellB]

1948 DODGE B-1-B 1/2 TON Pickup 6cyl 3.6L 1BL L-HEAD

The lower bushing on the distributor is worn out, and I need a distributor.

My distributor number is IAP4001-1. Bernbaum told me they only made these a couple of years, but they are interchangeable. Interchangeable with what, I do not know.

So if anyone knows a resource for used, reman, aftermarket, or someone who can rebuild it, I would like to know.

The HEI's are for 12-volt systems, and this truck still runs on 6-volts.

Hi Darrell,

I'm not an authority on which fits what (someone else please chime in) but I think the distributors are basically the same (and interchangeable) with one exception: The shaft length is either 5.25" long or 5.5" long depending on the displacement of the block 218, 230, or 251 I think.

1AT-4003A is 5.25" long. (I think this is for the 218 and 230 engines)

1AT-4102 is 5.5" long. (I think this is for the 251 engines)

Do you know the correct shaft dimension of the distributor your engine requires?

Yes limited models that ued this same disb. Instead of getting a new disb look for a person that rebuilds distributors and ask if they can replace the bushing.

The Bushing is an Autolite IG-579A. This bushing was used in all of the disb from 1938-1951

Darrell, Call Jeff at Advanced Distributors,(612)-804-5543. I sent mine to him this past summer for a complete rebuild. He was a great guy to deal with, the distributor was returned like new, and all in a couple of weeks.

Hope that helps,

Hank, I will measure. No problem. Who sells these distributors?

I also had my distributor rebuilt by Advanced Distributors within the last several months and they did an excellent job.

Ebay has them from time to time but I wouldn't count on it. I rebuilt those two. I'd sell the one I don't need (I think my 218 or 230 uses the shorter one). Is yours rebuildable? They are really not that difficult.

Seems like a good way to go:

Or if it's the bushing you need:
