727 build-unable to adjust rear band

yup. i pulled the lever pin, removed the lever, and grabbed the lugs; they touch with a ton of room underneath in between the band and the drum. i must have ordered the wrong band. i should have checked first i guess. i wouldnt have even thought to check engagement if you guys didnt mention it.
the trans is a 76 casting, and i must have spaced when i ordered the band. thanks, dudes. i'll let you know for sure tomorrow what i find
