[DeTomaso] 73 Stock front 4 piston caliper

Hey Guys and Gals

While inspecting and cleaning the front Girling 4 piston Calipers on my 73L, I managed to rip the dust covers on one of the smaller pistons. It has Girling no. 64321393 and "JLF" on it. I don't really want to spend $50 for a rebuild kit just to get a dust cover but will if I have to. 
Does any one know what other cars might use this dust cover or possibly have a useable old dust cover.

The kid behind the parts counter thinks Pantera is a rock band and can't cross reference the Girling SP-2691 rebuild kit unless I get him a year make and model of a car he has in his computer.

Thanks

Wayne
