anyone have a tunze 6100 impeller i can borrow to test my unit

[ls1boost]

i have a tunze 6100 which i belive needs a new bearing or impeller unit. looking for someone that has one that i can come over and switch out impellers for a second to see if i need just the $2 bearing or the whole unit or if its not the impeller i havent spent $40 to find that out.

thanks
