Engine is a 1992 5.7 out of a suburban or something
1 piece rear main seal
transmission is TH350

I can find it at summit for about $90 but that's SFI rated and I really don't need that...

is there a stock car out there that I could buy a flexplate for at autozone/vip/napa etc... that would do the trick???

Thanks in advance for any help you can give me, I'm kind of stuck until I figured this out or shell out $$$ For the SFI plate

 

Stock flex plate for a 87-92 305/350 Camaro/Firebird
