Front band adjustment along with long tube headers

My 68 came with long tube TTI headers on the 360. Prior owner never installed a kickdown lever or cable. So I am finishing up Lokar kickdown cable install and a fluid change.

I don't see any room to get to the nut to loose the adjustment and for sure no room to use a torque wrench. My only guess would be to drop the transmission crossmember and angle down the transmission.

What are you guys with long tube headers doing for band adjustments?

just snug the band slightly and back it off number of turns. Never used a torque wrench myself
