To everybody that replied,
thank you, all reply’s were very helpful and after spending a LOT of time measuring and comparing to MS drawings as well as from RBC Bearing Co and several others all the matches pointed to MS21150/MS21152/REP3H5/REP3M6A.
So long story short, I went ahead and ordered them from Spruce, there goes my next six tanks of gas lol.
Sam, could you please contact me at bearbait69@earthlink.net, I would like to talk to you a bit.
Again, a very big thank you to everybody that helped.
