Man, that is a quandry! Sounds like the shifter is pushing when it should be pulling or vice versa. If Carl's suggestion doesn't work, look to see if your V8 bell has a place to mount the fulcrum that was on the IL6 bell and return to using the original shift linkage. If it doesn't, then you're most likely going to need a date coded bell from a 55 V8 truck, which should have the fulcrum mounting.
