Lower ball joint question!!

[GMJimmy]

Years ago I remember having to replace entire lower control arms in a lot of cars because replacement pressed in ball joints didn't fit tight enough and could fall out. I've even seen where people tack welded them to keep them from falling out. That all changed when Moog came out with their REPLACEMENT Problem solver lower ball joint that was made a little larger with more aggressive serrations to hold them in place. This saved the lower control arm from the scrap bin for another pile of miles which usually made it to the end of the vehicles life. So here I am needing to replace my lower control arms in my 68 C10 because the threads the bushing screws into on one of the arms is stripped from previous owners attempted repairs and my new repop control arms (which I'm told are high quality??) don't have new ball joints installed. I have replaced OE ball joints with Problem solvers in a lot of cars over the years and they do fit tight, sometimes real tight, so my question is, has anybody here installed problem solvers in new repop A arms? Are there manufacturers that make standard size ball joints? TRW maybe?
Thanks
