Are they 4006UT for the M38 or 4006AUT for the M38A1.The M38 and M38A1 have different advances which is why one is M38 is UT and the M38A1 is AUT.

[Joe Gopan]

And you are aware that Distributor IAU-4006AUT Supersedes IAU-4006 UT in the latest M-38 ORD9 dated 1956?

[Radtech]

The advance curves are different between the two as well as the advance springs.Also the AUT is not correct for a production M38.

[Joe Gopan]

That's correct, but they updated to the IAU 4006AUT for a reason. Perhaps not so much on this particular installation, but some updates meant increased performance or reliability. The earliest Distributor (Not the ones being offered) with the early Ignition Filter was a time bomb and could leave the driver walking. I prefer reliability and upgrades that improved driveability to sitting alongside the roadway.

[Joe Gopan]

ORD 7358569 is the IAU-4006 AUT, you have 2
ORD 7355596 is the IAU-4006 UT, all will function fine in either the M-38 and M-38A1, both Jeeps could be found with either after having a distributor change.

Are the Distributors still available? Can you post some pictures, where are you located?
Who rebuilt them and when? When rebuilt were bushings and springs replaced?

Thanks
