95 pa ultra 91k 3.8 supercharged vin 1, approx 6 months ago i replaced the hb (which had the rubber torn),3 weeks ago replaced the hbbecause it was rattling again (rubber ok) - since then i have put in 2 new hb's from napa (made in china like the last) and both hb's broke at the keyway on the snout with in 24 hrs of installation. Always double checked that hb was completly seated. no vibration on initial start up. figured the first break was a faulty hb. just looking for feedback.[img]smileys/smiley5.gif[/img]

 

had a revelation and reinstalled the hb fromn 6 months ago, so far 3 days and no problems. purchased a new hb from gm and will install on friday. get what you pay for i hope $245.00 gm-- $108.00 napa. napa distributor thought there must be a bad lot. no @@@@ will let everyone know what happens.
