Still dealing with the vibration( 67 coupe 351w,T-5), I shimmed the rear axle about 3 1/2 degrees up.. The vibration is
less than it was, but it's still there. I know the trans is down more degrees than it should be. I'm looking at Ron
Morris mounts that will lower the engine 1/2". I looked at the way the fan fits inside the guard on the rad it's
centered ,but it's closer to the top than the bottom, it looks like I can go down a 1/2". The cross member may have to
be unbolted and shimmed down to clear the oil pan. I'm not sure if I will run into any other issues (clutch linkage)?
I'm thinking if I can lower the engine, that might let me raise the back of the trans to get the where it needs to be.
Currently using stock 69 brackets, and 69 motor mounts. I did talk to Ron Morris, he was very helpful he said
he's had cars set up right in spec (trans and rear end) and still had vibration. He said an aluminum drive shaft
cancelled the vibration. Just wondering my old driveshaft is heavier more weights on it ,(never had any vibration
issues with that one) is 1/16" longer than the new one. The yoke is on it is for the 4 speed toploader  I read if
you use this yoke on a T-5 it could cause problems with the T-5 tail shaft. Would I be able to swap drive shafts
for a test ride without doing damage to the T-5? If it worked out better I could put the new T-5 yoke on the old drive shaft. The only other thing I could do is cut out the transmission tunnel, which I really don't want to do. I'm
thinking some one has gone thru this before. THANKS FOR ALL THE HELP SO FAR!  mustang stu
P.S. Not sure if I should try swapping driveshafts before or after lowering the engine?
