I bringing this back up even though there are several threads about this. 3800 sites seem to have 2 different part# for ARP rod bolts and the l32 are about 20 bucks higher. After talking with ARP today part # 123-6002 they tell me will work on all 3800 and the bolt under head is 1.7" which is what my l32 rod bolts measured. My question is why do I see so many people saying the l67 bolts wont work in the l32 vice versa. ARP say it will fit any 3.8 from 1975 to 2006?
 


The thread pattern is actually different between the L67 and L32 rods.

ZZPerformance has the L67 ARP rod bolts and 3800Performance has the L32 ARP rod bolts.
