Starting 6.0L swap. Crankshaft flange depth??

I've got a question can't find an answer any where. So my 6.0l Has the 1.25 flange.I know theres an early and late model.which are two different sizes. Would i need to run a spacer to adapt it to my 700r4? All help would be appriciated. Thanks!!

I beleive Hughes makes a flexpalte to be able to bolt an LS engine to a 700...I'll edit my post when I find the p/n

EDIT: I found the parts...but I'm not going to post the p/n as I'm not sure which ones to use. Do a search on Summit for "Hughes flexplate" and you should find it.

EDIT EDIT: I look more at that summit stuff and it looked like it was only for a turbo 350 and 400...so keep digging! I'd do a search on LS1tech, they know their **** over there.

Come on nobody? How strong are the crankshaft/flexplate adapters?
