A&A was the one place for springs and weights. my old brain just can't remember things any more ! glad you got your end play sorted out ! i'm no expert by any imagination on 727's, but i have built several over the years, and have installed a ton of valve body shift kits, as well as modifying valve bodies without using kits, having no failures in the process with the one exception of having the low/reverse band strut falling out after assembly. i always refer to the books i mentioned because of my memory problem. hopefully, others with way more knowledge than me will chime in such as cope and kunkle, and others to make sure i don't steer anybody in the wrong direction ! those guys are excellent "proof readers" for my drabble !
