Throw-out arm boot.....anyone found a source for these?

[MVRCorp]

67 - 273, 3 speed, column shifter. I'm looking for the dust boot that goes on the bell housing for the throw-out arm. Who out there has found a source for re-pops?

Also the boot on the firewall for the cluch rod.

the paddock has both of them.
