Default 68 Firewall Grommets

I gutted my engine compartment to paint. now I an reassembling. The speedo & tach cables just went through the big holes in the firewall with no grommets ! I purchased the correct rubber grommets with the metal tabs on them but how do you get the cables through them ???? The ends of the cables are not removable !

I split the side of the hole in the grommet with a razor blade, then slipped the grommet over the cable.

Once it's installed into the firewall, no one can tell it was split.

Thanks guys......I will try slicing the rubber in the center. It seems to have metal around the perimeter with 3 tabs that hold it into the firewall hole so I can't really cut it to the outside edge !
