Need 4-speed Help

When I installed my Lakewood scatshield,it came with an adapter ring for where the tranny fits in the bell housing.You mentioned you picked it up at a swapmeet.Just wondering if you got the adapter ring with it?This could mean your tranny is not properly lined up causing shuttering,vibration.Just my 2 cents.Good Luck!!Don,t you just love the tiny fork hole?
