Dorman bushing is magnetic. looking through old thread Ken (Pontiac Dude) said even old ones were and no issues if a dab of grease.
McLeod has a 1380-1 Pontiac (as well as -7 extended) that are listed as oilite.

Back from my friends cabin. Measured the National I had vs. the NDH that was removed and they were close to each other using my 0.001 dial caliper. But, I didn't use the National for some reason (see later) other than the width was 0.352" vs. 0.354" (NDH). Real reason was 8 bearings vs. 9 on original.

So got the McLoed today Comparison to Dorman
Dorman -actual stamped 0174523 OD 1.3795 ID 0.595 thickness 0.436 mcLeod OD 1.3819 ID 0.5935 thickness 0.351 BOTH are magnetic. In their catalog it does not list the Pontiac as oilite whereas the SBF same OD is-different ID, and some GMs. They do make a thicker one for Pontiacs.

Dorman was snug but could push in with fingers so went with the McLoed it had to be tapped in with a little force

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
