found this teapot and slingy bearings look to be the same I think
Quoted from Del in a previous post
''You don't need to swap stems on the srad,k-series,busa,tls/r,etc yokes,just needs a bearing swap and modify the lockstops
You just need the slabby/ slingshot 32006 bottom bearing and a 32906 bearing,from Marksman,for the top bearing http://shop.marksman-ind.com/99-3540-5-30x47x12-taper-roller-bearing-32906-15086-p.asp ''
