chevs of the 40's has both the special bolts and the retaining clip. If those bolts come out it gets very ugly in there, I took mine apart after 28 years and now I know why the fella I bought it from rebuilt the transmission,(at least said he did) the bolts had obviously came out at one time. The bolts, the yoke, and the little ball joint areas was all beat up. He didn't even bother to dress the high spots caused by the carnage,just bolted it back together. Leading me to wonder what sort of work was done on the transmission.
