LS7 to 4L80E flexplate

[Bad Bowtie]

Hey Guys,
I'm in the process of helping a friend build his 93 Silverado truck he has an LS7 from a Z06 Vette and behind it will be a 4L80E for transmission. Does anyone know of an alternative to the 4L80E TCI flexplate that will fit with the LS7.
Hard to take the $320.00 pill if there is another option out there.

Thanks

Circle D referred me to TCI when I was looking for one. Had to wait about 6 moonths to get it in mid 2020

Here's a couple less expensive options, haven't tried them though.

Understanding flexplates for these LS motors have been all over the map for me. So Jody you advise that I will need a spacer with the flywheel. I have heard of that but thought it was for like 6.0 liter LS w/ 4L60 E. I read where some engines needed the spacer some didn't. I will look into the ones you listed.

I ran a GM Performance flex plate with my 4L80E and shredded it during a backfire while cranking. I could not get perfect engagement with this setup.
I bought a TCI flexplate because it such a nice piece but pricy. SFI certified.

Bottom line:
Get a good one.
I didn’t and cost me a full engine pull because I tried to save $$$
