I now sell these with an anti-static laminate bonded to them.  I prefer those to regular felt as there is less graphite shed on some tapes.
 
An economical, easy to cut, peel and stick replacement felt for those 8 track tapes that used the felt on a copper pressure spring pad. These are thinner than the original felt (these are around 1/16" or less thick). Which makes them easier to cut. Though if you aren't going to open up the cart to replace the felt, I recommend my pre-cut anti-static, or regular felt tabs.  They are a little thicker and easier to install  if you aren't opening up the cart.  
 
Simply cut the length you need, peel and stick! (You WILL need to remove old adhesive from the copper piece or these won't stick properly). Comes with five 6 inch long strips Enough to do roughly 25 to 50 tapes, depending on the sizes you are dealing with (There were 3 different sizes used on the carts, Small, Medium and Large).
 
I offer a choice of 3 colors. Brown, Black or Cashmere Tan.  I also offer a variety pack which includes 3 strips of the brown felt, one of the black felt and one of the cashmere tan felt.
 
Copper strips are for demonstrative purposes only and are not included.
