I keep breaking ears somthing to be expected or can i do somthing to help prevent it? I still have a stock cross member with a poly urethane tranny mount with a inner lock on it. Thanks

Is the driveshaft straight? (rear end in line with motor/tranny)
How far does the driveshaft go into the tailshaft? Should have about 1" of yoke out of the tailshaft.
Do you have to pry the mounts in place?

WHAT KIND OF SHAPE ARE YOUR ENGINE MOUNTS IN? AND ARE THEY BOLTED IN THE PROPER LOCATION?

another thing to look at is the angle of your driveline. the driveshaft needs to angle down from the transmission and up from the rearend. if the driveshaft angles up from the transmission, then you have a condition known as "broken driveshaft syndrome". you will have all sorts of bad vibrations and broken parts if this is the case.

ears break from your bellhousing not being aligned usually on initial installation.

does your tranny fall right in the hole and the bolts line up easily? dont use the bolts to pull it together.

test it with the bellhousing out if you can that way your not checking the pilot brg alignment etc.

this may sound stupid but check the pilot bushing/bearing.used to help work on an ACT late model and he btoke six trannies and only reason was pilot bushing.we found this out after burned a clutch up and put a new one in and when we stuck the alignment tool in it was like throwin a hotdog in a 5 gallon bucket.we REALLy felt dumb after that because we never broke anather in 2 years of racing after. food for thought.

do you have your dowel pins in place so your trans will bolt true to the engine? many times a machine shop will take them out.
