i have a 49 chevy pickup with a 69 nova rear and front end. i have vibration in the seats and etc. it is more noticable at around 40 mph and above. it is not a bad vibration but iratating. i have had a new drive shaft made at a machine shop and still have the same problem. can it be in my rear end. also what gears will be best in the rear end for street and highway 308 or 342.

1. Have you had the tires balanced?
2. You say you had a "machine shop" make a new drive shaft. Was this shop setup to balance a drive shaft?
3. Could be a bad belt in a tire.

I would also add, check your pinion angle.

i'm wondering if u have the 2 pc wheels with the floating spacers inside ????? if u do pull the wheels, turn inside up and put in all your lugs. drill two 1/8" holes (not all the way) and put in split pins to hold them.. now get them balanced... those floating centers drove me nuts and this was my fix...
