My th350 will be here tomorrow, and the converter has a pilot spacer already for the ls1 conversion. My question is, what flexplate can I use. Only 98. 98-99, or any thing other than the $330 tci flexplate. Im trying to do my swap on a budget, but not skimp out on parts too bad. I need help on this one guys.

 

SDPC is sponser TCI flexplate is like $190 from them

just put a wanting to buy 98 flexplate or one from a 6.0L those will work too. IT just need to have the dual bolt pattern. I believe the guy I bought mine from had another one lying around. Jantzer98SS, send him a pm.

 

 

I got one comming now. Thanks guys.

 

i run stock

 

The 1999 flexplates are not the ones in issue, it is the units that were used in 2001 & 2002 that were thinner.

When my TC was replaced, the shop had to remove 3 of the six bolts anyway, so I figured for no extra cost, provide them with the TCI flexplate, and be done with it. I had purchased the longer ARP bolts prior to the installation.
