Need help. 4l80E to 4l65E flexplate bolts
I have started the swap on my 84. The set up is a 04 lq4 with a 4l60e upgraded to a 4l65E. I have the flexplate ready to mount but cant seem to find the smaller flexplate bolts in any of the parts stores around here like advance, etc. The 4l80e that was on here had the flat flexplate with the spacer. Any suggestions?

Re: Need help. 4l80E to 4l65E flexplate bolts
had this info somewhere......just can't find. M11 maybe?
otherwise.....order some aftermarket replacements thru Summit, Jegs, or others that carry ARP bolts? You don't want to use some low grade bolts for this.

I ordered some arp bolts for mine...actually it was converter bolts, but I've seen the flywheel ones too....

I went looking for the crank shaft/flywheel bolts and I couldn't find crap. The thread pattern is metric but looks almost standard. I thought it was M12 1.75 according to the thread plate chart in advance auto.

Here is the bolt pattern. Strange that no store could match it and they all wanted to give me a small metric pattern.
