Like I said, slant six boxes have a bushing, not needle bearings. Others stated this in prior posts. My 64 Valiant convertible box had bushings. The O.P. didn't bother to tell us what engine he/she has. Prior posts in the last 6 months discuss what grease to use. I packed mine with moly wheel bearing grease. Probably the biggest concern is the grease cooking away from the exhaust heat. I removed the big locking nut with a hammer and chisel after soaking in WD-40, but a CA car w/ no corrosion. Instead of the special tool in the manual to unscrew the input shaft loading nut, I used 2 Phillips screwdrivers in the holes w/ a long pry bar across them. Mine looked worse inside, with just a small amount of dried-up grease. Probably hadn't been opened since 1964.
