Distributor ID

I would like to know what distributor that I have. There is no tag (data plate) on it. The two "tune up" kits that I have bought for it have rotors that are keyed 180 degrees opposite. If I knew what distributor it was, I will not be shooting as much in the dark.

Is there a specific characteristic that tells the IAD from the IAY series?

 

couple of exploded views of IAD 4041 and IAY 4401
cap and rotor are different diameters and lengths

 

Re: Distributor ID (and the pix)

For those who just like the pictures:

the distributor in question

 

pic of the rotor would be helpful if available

 

Here is the rotor:

Distributor rotor

 

and the rotors you are receiving in the kits are identical in every way to the one currently being used, other than being keyed 180* opposite ?

 

Right. It's realtively easy to swap the wires, but I feel so dumb doing that.

 

well, this may not be much help
for the rotor you have pictured there are 2 different Jeep p/ns
A-1658
and
A-5294
I don't have either to compare side by side
but maybe someone, parts store, can cross the OEM numbers for you

 

I suppose you could also remove the dist, loosen the oil pump, rotate the oil pump 180* then reinstall the dist shaft also 180*
is number one not at the bottom, to the right on the wire connection?

 

I can get it to run fine. But, back to my original question...What is it?

 

IAY
based on your pics

 

Many thanks.
