Default SFI Flat Flexplate?
I am putting a 6.0L LQ4 into a dragster with a poweglide transmission. The engine has the extended crank flange. I cant seem to find a SFI certified flexplate that will work. Everything says it will not work with the extended crank. Has anyone seen a flexplate that will work? Can I use one of the flexplates that comes with a crank spacer & leave out the spacer?

I have a LQ9 mated to a powerglide in an altered. I used a TCI kit 399753, flex plate and adapter to mate the converter hub to the crankshaft pilot. But I'm not familiar if the crank of the lq4 and the lq9 are different. Just call them and double check.
