Carl, yes.
6571: I always switch to tapered rollers. The kit 47-59 includes inner and outer tapered roller bearings, race (also called cup and cone) and seals for less than $100. Albeit 58 is a lucky year because the stock ball bearings and seals seem to be cheaper than pre 58...but not cheaper than the kit.
Just one vendor exampleI have also used a different kit made for disc conversion.
The above kit is supplied to Speedway, and many other vendors, by CPP. The price is fixed.
There seems to be several sizes/designs for 58 1/2T front bearings? Don't know why but double check ID's and OD's of kit bearings to your bearings.
