Part #12602448; going with a Yank converter and figured it would be a good idea to upgrade during the install. Is this a direct replacement for the stock LS1 flexplate? Any other things necessary like spacers or longer bolts? Search turns up very little info about the swap. TIA

 

Anyone have info to share?

 

same number of teeth to work with LS1 starter?

 

I think they both have 168 teeth. They're also both 14". And that's about all I can find.

What I want to install is an LS2 flexplate and Yank converter with ARP TC and flexplate bolts. I want to know that all those parts are compatible before I tear into the trans, if possible.

 

honestly, i'd stick with what is tried and true, a TCI SFI flexplate, a little more but gets the job done nicely

 

Have heard of various problems with the TCI. Since my car doesn't see much "abuse" I think the LS2 plate would be more than sufficient for it (still running the stock '02 flexplate), and at a decent price. I'm also one of the few that thinks GM engineers may even have some idea what they're doing

 

well, as far as that goes you'd be fine with a 98-99 flexplate then.

 

That's an option. I figure the LS2 plate is probably similar to the earlier design.

All the old part numbers I looked up were superceded by the LS2 part. I even found an old pic posted:
