Need new balances for my windows

Hi. I need a four of the nylon sash cam for my windows. My block and tackle measure 25.5" metal end to metal end. The cam sash's measure 5/8" width on both top and bottom. No "wings"...they are not wider at the top than at the bottom. I measure a width of 5/8ths, a depth of 9/16ths and the height comes in at 1 15/32nds. I need a couple of the take out clips too. Pics attached

Thanks!!!

Hey Tom...thanks for getting back to me. At this point I only have one broken nylon sash cam and one...a bit distorted.... metal take-out clip. So...I guess it just depends on how much they cost in terms of buying a couple spares each. Dave
