well i will just have to find a GP in a junk yard and use it as a test even though GPs are super hard to come by in my local junkyards i've only seen one and it was totally stripped already with no salvageable but ill look.
What? How? The yard I go to has literally like 50 of them. SE's, GT's, GTP's...everything. You can get basically ANY part you need for a GP from that place.
2001 Regal GS, PLOG, 3" DP, 1.9's/L76 springs. 21* of timing on a 3.4"
