T 56 swap question

I have not yet, but I did do it with a BB and Viper trans with a single disc clutch. I had to use a .460" spacer under the throwout bearing for clutch clearance. On the Gen III Hemi I'm gonna use a McLeod 6913-07 rst dual disc clutch that happens to be a Mustang application and is a stock replacement although no Mustangs had dual disc clutches. The SB Mopar to Viper T56 bellhousing is gonna work fine just without one bolt. Here is the McLeod's description and they dont say much but you can see that the clutch cover is alot more shallow to accommodate the extra disc and floater plate.
