King doesn't call any of its bearings "heavy duty" as far as i can tell
from the catalog and literature they sent.

>>4. King makes bearings, of which some are heavy duty applications. John K
>>recommends KIng heavy duty. TRF supplies King, not sure if they are
regular
>>or heavy duty. Art D, did you ever find out if King has the heavy duty

>>5. There may be a heavy duty Glacier or Vandervall for MGB or Metro
>Turbo(?)
>>that would fit. I talked to Bob Yarwood, who Babcock said may have a
supply

MGB
>>(gag). He said they were slightly wider but the only mod required was

>>6. Clevite 77 bearings are trimetal, but only aluminum ones are made for
